change sheet1 to sheet2
-48.13
sheet2
@phoebe_90 if you want to overwrite the existing column, instead of creating a new one:
@phoebe_90 you just need to use a formula tool like so:
Mutiply the column by -1
First of all, change the data type for the Amount field to either Double or Float by using select tool, then use the formula tool ([Amount]* (-1)) to get the desired result.
looks good
