I have two issues as the following
1. I have used the formula below to calculate tax percentage. (Data Type: V_WString, Size 4). However, the result is inconsistent. As you can see from the screen shot below, row 10 and row 11 both did the calculation, but in a inconsistent format. I'd like something to show as either 7.74% or 0.0774. Either format will be fine, but I'd like to have consistency across the file.
[Sales Tax Amt]/[Sum_Line Item Amount]


2. In Customer column below, I'd like to move the leading zeros. I used formula below to Trimleft, but I received an error message that I am not sure how to fix.



Any help will be appreciated. Thank you!!
