Let me ask you a couple of quick questions to make sure I fully understand your problem. For starter, can you please show me the data?
User 17/09/2018 - 09:04
How do I show you
Excelchat Expert 17/09/2018 - 09:05
You can either send me the file or you can copy/paste on the blank spreadsheet on the right hand side.
User 17/09/2018 - 09:05
It is on Google Drive ...
Excelchat Expert 17/09/2018 - 09:06
In that case, you can share the link to the file, or copy/paste data in the blank spreadhsheet.

Excelchat Expert 17/09/2018 - 09:06
Thanks, please make sure you grant the necessary permission before sharing..
User 17/09/2018 - 09:06
Let me know what I need to do
Excelchat Expert 17/09/2018 - 09:07
You have to make the file publicly visible before sharing the link.
User 17/09/2018 - 09:07
Excelchat Expert 17/09/2018 - 09:07
Great!
Excelchat Expert 17/09/2018 - 09:08
Now please tell me what you need by referencing to appropriate sheet and cell names.
User 17/09/2018 - 09:08
On this tab
User 17/09/2018 - 09:08
STEP 3a - Deal Summary
Excelchat Expert 17/09/2018 - 09:08
I'm there..
User 17/09/2018 - 09:08
Cell G2
User 17/09/2018 - 09:09
That is where I would like the formula
User 17/09/2018 - 09:09
The formula needs to sum the following cells
User 17/09/2018 - 09:09
C8 and C14 from the following sheet
User 17/09/2018 - 09:09
STEP 3b - Project Costs
User 17/09/2018 - 09:10
Based on the address in cell C1 on both sheets matching
Excelchat Expert 17/09/2018 - 09:10
C1 might change?
User 17/09/2018 - 09:10
Yes
Excelchat Expert 17/09/2018 - 09:11
If the address doesn't match, then?
User 17/09/2018 - 09:11
Empty cell or maybe a message in the cell to explain that error
Excelchat Expert 17/09/2018 - 09:12
Explain error can be a vast array of information. But empty cell is a definite.
User 17/09/2018 - 09:12
Sure thing - I can add an IFERROR after
User 17/09/2018 - 09:12
Just something like "Addresses Don't Match"
Excelchat Expert 17/09/2018 - 09:13
Okay, this can be done.
User 17/09/2018 - 09:13
Excellent
Excelchat Expert 17/09/2018 - 09:14
So, based on what you have shared, you need to add cell C8 and C14 of STEP 3b - Project Costs in STEP 3a - Deal Summary sheets G12 if the address at C1 of both sheets are the same, otherwise you would like to see an error "Addresses Don't Match".
Excelchat Expert 17/09/2018 - 09:14
User 17/09/2018 - 09:14
I believe so
User 17/09/2018 - 09:15
Into G2 not G12
Excelchat Expert 17/09/2018 - 09:15
Great, since I don't have edit access to your file, I will share the formula you need to use in G12.
Excelchat Expert 17/09/2018 - 09:15
Okay In G2.
Excelchat Expert 17/09/2018 - 09:15
My apologies.
User 17/09/2018 - 09:16
I have allowed you edit access
Excelchat Expert 17/09/2018 - 09:16
It would need 2/3 minutes.
User 17/09/2018 - 09:16
Sure
Excelchat Expert 17/09/2018 - 09:16
Thank you
Excelchat Expert 17/09/2018 - 09:17
=IF(C1='STEP 3b - Project Costs'!C1,'STEP 3b - Project Costs'!C8+'STEP 3b - Project Costs'!C14,"Addresses Don't Match")
Excelchat Expert 17/09/2018 - 09:17
This is the formula.
Excelchat Expert 17/09/2018 - 09:17
Let me tell you how this works.
User 17/09/2018 - 09:18
It need to go in 'Purchase/Holding Costs' not 'Asking Price'
User 17/09/2018 - 09:19
Perfect
Excelchat Expert 17/09/2018 - 09:19
My sincere apologies, I have corrected it.
User 17/09/2018 - 09:19
Thank you
Excelchat Expert 17/09/2018 - 09:19
Does this solution solve your problem?
User 17/09/2018 - 09:19
Excellent
User 17/09/2018 - 09:19
How did you do that
Excelchat Expert 17/09/2018 - 09:19
The formula I used is =IF(C1='STEP 3b - Project Costs'!C1,'STEP 3b - Project Costs'!C8+'STEP 3b - Project Costs'!C14,"Addresses Don't Match")
Excelchat Expert 17/09/2018 - 09:20
IT first checks whether C1 of Step 3a sheet is equal to C1 of Step 3b sheet.
Excelchat Expert 17/09/2018 - 09:21
C1='STEP 3b - Project Costs'!C1 this is the part of the formula.
User 17/09/2018 - 09:21
Sure
Excelchat Expert 17/09/2018 - 09:21
Then next part is 'STEP 3b - Project Costs'!C8+'STEP 3b - Project Costs'!C14
Excelchat Expert 17/09/2018 - 09:22
This tells excel to sum C8 and C14 of Step 3b sheet if the first part of the formula returns TRUE.
User 17/09/2018 - 09:22
I see
User 17/09/2018 - 09:22
and then the error if not
Excelchat Expert 17/09/2018 - 09:22
Meaning this part will be executed when the address matched.
Excelchat Expert 17/09/2018 - 09:22
Yeah, otherwise the error message is returned.
User 17/09/2018 - 09:23
So it only required a simple IF formula - nothing like Index or Match was required
Excelchat Expert 17/09/2018 - 09:23
Yes a IF formula is sufficient and efficient in this case.
User 17/09/2018 - 09:24
Excellent - I am really grateful for that
Excelchat Expert 17/09/2018 - 09:24
User 17/09/2018 - 09:24

Excelchat Expert 17/09/2018 - 09:24

Excelchat Expert 17/09/2018 - 09:24

User 17/09/2018 - 09:24
Is it really expensive - as I have so many problems
Excelchat Expert 17/09/2018 - 09:25
I really don't have any information on the pricing. I am hired to solve problems.
User 17/09/2018 - 09:25
