If you have a total hours field that you want to multiply this by $120.00 to come up with a total due - how can you do this in Adobe 9.0 Pro form?
You can use the built-in functions in AcroForms to multiply the two fields together.
When you right click on a form object you can select 'Properties' from the alternative menu. This provides you with several options for the layout, appearance and interactive aspects of the object.
Go to the Calculate tab and you will see that you have four options:
- Value is not calculated (not what we want here)
- Simplified/assisted method for specifying the calculation (easiest way for simple calculations)
- Simplified field notation
When you select the assisted mode, you can select from the dropdown that you want to multiple the fields. Then click on the "Pick..." button. This will open a dialog where you can select the fields that you want to multiple together. In this case "HoursTotal" and "RatePerHour".
Click OK and thats it!!!
