Let me show you an example of how to use a Vlookup
User 08/06/2018 - 11:39
I am quite familiar with how to use Vlookup. Just can't figure out how to get around this problem. My excel file is over 50mb, so can't send it.
Excelchat Expert 08/06/2018 - 11:39
Alright, no problem
Excelchat Expert 08/06/2018 - 11:40
Could you please tell me what are you having problems with?
User 08/06/2018 - 11:40
As explained in my initial comments
Excelchat Expert 08/06/2018 - 11:41

My VLOOKUP formula won't work when the value which the "lookup cell" is accessing is derived from a formula. If I manually transfer the formula derived value, for example the number 256) to a different cell, and then ask the VLOOKUP formula to look at this new cell, then the VLOOKUP formula works just fine. What's going on?
Excelchat Expert 08/06/2018 - 11:45
Alright, did you check if the formula works on another cell? Before the vlookup?
Excelchat Expert 08/06/2018 - 11:46
It's hard to say like this without having a look at what's going on.
Excelchat Expert 08/06/2018 - 11:47
Could you please copy some partial data here to show what are you trying to do?
Excelchat Expert 08/06/2018 - 11:49
Did you check if the lookup value is on the leftmost cell?
Excelchat Expert 08/06/2018 - 11:50
May I know which error are you getting?
Excelchat Expert 08/06/2018 - 11:50
#NA, #VALUE OR #REF
Excelchat Expert 08/06/2018 - 11:51
Are you still here? I'm sorry but I am not getting any response.
User 08/06/2018 - 11:52
Yes, I can tell the formula derived value to go to any cell I want, but the VLOOKUP function just won't work if that different cell is directly derived my formula or if electronically copied from orginal formula derived cell. But as long as I manually copy the numberic value into a new cell, then have VLOOKUP search that new cell, then the VLOOKUP function works fine.
User 08/06/2018 - 11:52
Yes, the error I get is #N/A
Excelchat Expert 08/06/2018 - 11:52
Well, I get what is happening.
Excelchat Expert 08/06/2018 - 11:53
But without looking at how things are working, its very hard to say what's wrong.
Excelchat Expert 08/06/2018 - 11:53
Well, let me tell you the reasons for an #N/A error.
Excelchat Expert 08/06/2018 - 11:54
Firstly, if there is a typo in the lookup value. I.E. if the formula is not correct.
Excelchat Expert 08/06/2018 - 11:55
Secondly, if you are assigning TRUE as the third parameter, as a approx. match but the lookup value is smaller than the smallest value in the list
Excelchat Expert 08/06/2018 - 11:55
*value in the lookup column.
Excelchat Expert 08/06/2018 - 11:55
Next, if you are looking for an exact match and the match is not found.
Excelchat Expert 08/06/2018 - 11:56
Or, the lookup column is not the leftmost column.
Excelchat Expert 08/06/2018 - 11:56
Another reason is if numbers are formatted as text.
Excelchat Expert 08/06/2018 - 11:57
Lastly if there are leading or trailing spaces.
Excelchat Expert 08/06/2018 - 11:57
Did you check for these?
User 08/06/2018 - 11:57
I know the formula is correct because it works fine if the lookup cell is simply a manually entered value
Excelchat Expert 08/06/2018 - 11:57
Then I guess it is a problem in the format
Excelchat Expert 08/06/2018 - 11:57
Please check if the format is correct and if there are extra spaces.
Excelchat Expert 08/06/2018 - 11:58
Not the VLOOKUP formula
Excelchat Expert 08/06/2018 - 11:58
The formula that the lookup value is derived from
Excelchat Expert 08/06/2018 - 11:58
Did you try it in another cell to see if the returned value is right?
Excelchat Expert 08/06/2018 - 11:59
What you can do is copy one or two rows here at the Excel Online panel on the middle of the screen.
Excelchat Expert 08/06/2018 - 11:59
There has to be a reason among these. These are the only reasons you get a #N/A error.
User 09/06/2018 - 12:00
Yes, all these were checked and don't apply
Excelchat Expert 09/06/2018 - 12:01
I am afraid it is not possible for me to diagnose the problem then.
Excelchat Expert 09/06/2018 - 12:02
Could you please modify the data and use a sample one and show me what you are trying to do.
Excelchat Expert 09/06/2018 - 12:02
Just make up some data.
Excelchat Expert 09/06/2018 - 12:02
Show me the formulas you are trying to use.
User 09/06/2018 - 12:08
Your excel screen seen by me is stuck and nothing I do can get it to accept entries, so will call it a lost cause with you for now.
