I'm Stuck!

Cell J7 is a value coming from a spinner control. I'd like the sum of any numbers above a certain threshhold, which is controlled by the spinner, I keep getting 0, but if I manually enter a number into the formula, then the SUMIF will work. Can I not use spinners in a formula?

=SUMIF(G6:G138,">J7",G6:G138)

Thanks!
