Acrobat Interactive Form Tax Calculation
Hi, I'm currently a college student working on a project to create an interactive PDF form using a combination of InDesign and Acrobat. So far I have everything figured out; however, I'm trying to figure out how to format the invoice form to calculate an 8.25% sales tax rate using the information in a "Subtotal" field (the Subtotal being the sum of 3 other fields). Unfortunately, I have not found what formula to use to calculate the sales tax. Attached are what I have so far. I have used "Subtotal 1*0.0825", "Subtotal1*0.0825", and "Subtotal1*.0825" in both the Simplified field notation and the Custom calculation script sections and am unsure of where I'm going wrong. Thank you for any help in advanced!
