Isn't this the same problem that Geoff Canyon just solved with a delightfully opaque one line solution in a recent thread:

function roundUp x,i -- rounds x up to the next i
 return x div i * i + item itemoffset((x mod i > 0),"true,false") of (i,0)
end roundUp

When I click the increase button, I want it to increase to the next highest value that is evenly divisible by 20. So if the field has a value of 19, a click will set the value to 20. If the field has a value of 121, a click would increase  it to 140.
