Calculating reverse sales tax

[lloydh99587804]

I have a simple form with 4 fields “After Tax”, Sales Tax”, “Tax Rate”, and Before Tax. I would like to enter the after tax amount and the tax rate and have it populate the sales tax and the amount before tax. I think my problem is in the Sales Tax calculation Custom Calc Script

Thank You

You can enter this formula as the Simplified Field Notation option under the Calculate tab of C3.

Thanks you for your quick response, I checked and made sure that the Calc was in the Simp Field. Below is the what the calc results are showing. if the calc is working it should be total prince $3.75, Tax Rate 9.12500 (this is a Numeric field) cannot get the Percentage right if the field is set as a % field, Taxes $0.33 and the before tax $3.44

Solved, Once I got the % to work as a percentage field rather than a numeric field everything calc correctly
