Maybe you want to use DoubleVar or IntVar here?

Or float(varAmount.get()) |
int(round(100 * float(varAmount.get()))) here

Sounds like you selected columns are strings, not numbers.
Remember '123.5' + '-23' is '123.5-23', while 123.5 + -23 is 100.5
You need the amount column of the transactions table in the gadfly
database to be a numeric type, not a string type.
