calculations

If the name of the Total taxable field is "Total taxable", enter this as the custom calculation code for 4:
event.value = this.getField("Total taxable").value * 0.0125;
Also, make sure that the form calculation order is 1 then 2 then 3 then 4.

There are a number of ways to do this. But first, let us review the relationship between a percentage number and a decimal number. A percentage number is a decimal number multiplied by 100, so if I have 1.25% that number is the same as 0.0125, and when you perform a tax calculation for computing a sales tax of 1.25% times a total taxable amount, one multiplies the total taxable amount by 0.0125.

If you are going to cut and paste provided JavaScript and you are going to change a field name only change the text for the field name between the quotation marks. All character strings begin and end with quotation marks and the quotation marks must be matched pairs. Also you have to use a very simple text editor that does not do any special formatting like Window's NotePad or Acobat's builtin editor.

There are a couple of ways you can accomplish this using the techniques described in [url=http://www.acrobatusers.com/tutorials/2006/form_calculations]How to do (not so simple) form calculations[/url] by Thom Parker.

First you need to have a couple of form fields. So assuming you field names are as follows:

TotalTaxable for the "Total Taxable Amount"

TaxRate for the Sales Tax Rate formatted as a percentage with a default value of 0.0125 - note that JavaScript is treat this value as if it were multiplied by 100 for display and use the default value of 0.0125 for calculations.

SalesTaxAmount for the amount of sales tax being charged, The Total Taxable Amount times the Sales Tax Rate as a decimal number

For the "SalesTaxAmount" field you can use one of the following calculation options:

For the "Value is the ____ of the following fields:" option:

Select this option. Use the 'Product'
Select the 'TotalTaxable' and 'TaxRate' fields
Click the 'OK' button to lock in the fields.

For the "Simplified field notation" option you can use:
TotalTaxable * TaxRate
or use this code:
TotalTaxable * 0.0125
For the 'Custom calculation script' option you can use:

I am using Acrobat 9 Pro for Macintosh. I created a pdf out of InDesign. I'm trying to make it an interactive/fillable pdf.

Field X
Field Y
Field Z

Field Z would be the result of Field Y being divided by Field X.
All three fields are formatted as a number, decimal places “2,” no currency symbol. Field values are not validated. For Field [Z] in the calculation, I checked “Simplified Field Notation” and entered: Y / X

Field [Z] would be a result of division [Y divided by X]. It calculates correctly, but pop up messages keep appearing all over the document when you try to enter information in other fields that say: The value entered does not match the format of the field [Z]. And then it pops you back to the page with that field on it [Z].

HELP! How can I rectify this problem?

Need response ASAP. Thank you.

Search the forums for division. You will need a custom JavaScrpt for this calculation.
