Ok. I am referring the sample.
User 08/05/2018 - 08:42
in the column I have labelled 'to next mark' I want to know, how many marks it is until the student reaches the next grade...
User 08/05/2018 - 08:42

Excelchat Expert 08/05/2018 - 08:42
Sure. I got it.

So how do I do that please?
Excelchat Expert 08/05/2018 - 08:43
I am working on the formula.
User 08/05/2018 - 08:44
Ok thank you
User 08/05/2018 - 08:47
and so that if I change the 117 to 118, the number will automatically update to the right number :) Thank you

=index(Sheet2!A:A,match(B2,Sheet2!A:A,1)+1,1)
Excelchat Expert 08/05/2018 - 08:48
I have used match and index formula to get the next highest number.
User 08/05/2018 - 08:50
It doesn't like it when I copy it over and amend...
Excelchat Expert 08/05/2018 - 08:50
Excelchat Expert 08/05/2018 - 08:51
I have copied the formula to the next cell. It is picking up the right number.
User 08/05/2018 - 08:51
the B2 in the formula, is that on sheet 1 or 2?
Excelchat Expert 08/05/2018 - 08:51
In Sheet1.
User 08/05/2018 - 08:51
and A:A is that the whole of column A?
Excelchat Expert 08/05/2018 - 08:51
That is referring current matk.
Excelchat Expert 08/05/2018 - 08:52
And A:A is used in general for the whole column in sheet 2
User 08/05/2018 - 08:53
Yes I see what you have done and it works, however I need to next mark to say 3...
User 08/05/2018 - 08:53
tells me the difference
User 08/05/2018 - 08:53
so it tells me...
Excelchat Expert 08/05/2018 - 08:53
User 08/05/2018 - 08:54
no, I want 'to next mark' to tell me the difference between the '117' and the next mark up eg...to next mark would then say '3' in the row
Excelchat Expert 08/05/2018 - 08:55
Ok
Excelchat Expert 08/05/2018 - 08:55
=index(Sheet2!A:A,match(B2,Sheet2!A:A,1)+1,1)-B2
User 08/05/2018 - 08:55
Thank you!
Excelchat Expert 08/05/2018 - 08:55
