Excel/Sum function not working - returning zero

If you extract numbers with a string function such as MID you must convert the new string to a number. The easiest way to do this is by multiplying the result by 1.

I had the same problem.  I had IF formulas returning a 1 or 0 depending on other criteria in the row.  When I wrote my IF formula, I put " " marks around my TRUE and FALSE returns.  Once I removed my quotes and wrote ,1,0) my numbers started summing up.  I noticed you said you had formulas in the column where SUM did not work.  Hope this helps.
