Excel problem

See the attached excel sheet. One of you brainiaks came up with formula I have in Column H.  All I know how to do is paste it into column H and then go find the differences.  It helps me find numbers that don't match and I use this to reconcile our Amex account. Anyway, today something is wrong.  Normally after I run the formula in column H, it will say "false" when it encounters a difference. I have isolated all the difference and removed them to Column E.  Now that I have done that, column F should have the same total as column G.  But they are off by a couple dollars. Why?  Maybe I am just stupid today, but can't seem to find any cell in F or G that doesn't match. match-formula.xlsx
