So with my example above store #1 has 1 '0' (column K) before there is a '1'.
Store #4 Has 8 '0's before there is a '1'.

Can anyone suggest a formula on how to do this calculation?

Your labeling is a little confusing... you seem to indicate your values are in Columns A:K, but that would mean the Store column would not exist? So I'll give you two formula for the two different possibilities and you pick the one that matches your actual setup.


Store in Column A, Data in Columns B:L
-------------------------------------------------------------------
=12-MAX((A2:L2=1)*COLUMN(A2:L2))


No Store column, data in Columns A:K
-------------------------------------------------------------------
=11-MAX((A2:K2=1)*COLUMN(A2:K2))


Note: Commit these formulas using CTRL+SHIFT+ENTER and not just Enter by itself

Thank you so much for the fast reply. I am doing CTRL+SHIFT+ENTER and then pasting in the formula and I keep receiving: #value!. Any suggestions?

That is the wrong order... paste the formula into the Formula Bar, then press CTRL+SHIFT+ENTER.
