Hi Jan,

I have to sheets, with app. 140.000 cells, from A1 to DU1140. Both sheets has Unique numbers in column A and headers in row 1. The first sheet contains actual prizes, for different items. There are only prizes in some cells, and what cells are empty and filled are not patterned in any way, its almost random.

The otherf hseet is updated with new prizes, which can be in same or other cells as in sheet 1. Now I want to insert a lookup formula in the cells, and only the cells in sheet 1, that has already numbers in them. This formula should look up prizes in sheet 2, if such exist and return them to sheet 1, if the corresponding cell in sheet one is not empty. If it is, should not be inserted.

a IF formula needs 3 arguments and the structure is
=IF(Condition; True Part; False Part)

A nested IF formula looks like
IF(Condition1;True Part; IF(Condition2;True Part;IF(Condition3;True Part;False Part)))

To get the correct result the conditions must be listed from highest
priority to the lowest.

What is your order of priority? And what Excel version do you use?
