Thanks for replying!
Because the sheets are not quite identical
for example:
In cell A5, I will have the project number 156565-001 in the more populated document
In the new document, in cell A5, I have 165656-001. But the project number 156565-001 is still present in the new document, but is in cell A34.
So.
I need a way to match what is in cell A5 and A34.
Ideas?

Thanks!
