Hello,

I am trying to make an Excel-spreadsheet, based on Sudoku puzzle.

So , cells a1 to i1 have to be filled with the numbers 1 to 9, in
random order.

As you see, a1 to i1 is only filled with 4 and 6.
In columns k to s you can see which numbers are not used, so in this
example
in row 1, it is 1,2,3,5,7,8,9

The problem is, I want a formula to put on k1, with the following
needs: - check for a1 to i1 if number 1 is on it. In this example
NO. - if NO, then on k1 the number 1 has to appear
- it YES, then on k1 the number 1 has to disappear.

if((b1:j1)=1;" ";"1") is not working. What is the solution ?!?!?!?

If I have 1 formula, I can fill the other cells.

Thanks in advance, for helping me.

Greets,
