I need a Javascript that will allow me to calculate different tax percentages on a form. an example would be $132.00 total sales with 7.25% tax.

I have an adobe variable data .pdf I want to be able to calculate the tax rate or tax percentage. How can I write a Javascript for this?

Is the rate fixed? If not, where is it coming from? What are the names of the fields involved?

[carenm90738856]

The tax rate will be different from county to county.  I have it called tax rate and and total with tax.

[try67]

So do you have like a drop-down field with the county names?

[try67]

Or do you want the users to enter it themselves?

I enter all the information on this form.

Then you don't need a script, simply multiply the total by the tax rate to get the total tax amount. You can add that value to the total to get the total (incl. tax).

that is what I did originally it did not calculate right. the dollar amount for 132.00 x 7.25% should be tax of 9.57=$141.57 but on form it calculate to $139.25. I tried it several different way and cant get it to calculate right.

The value of a percentage field needs to be between 0 and 1 to work correctly. If you're using a value between 0 and 100 you need to divide it by 100 first.

I manually enter the tax rate.
