I need to have an adobe acrobat form calculate a percentage. I have a field named, value_a that I need to multiply by a user entered value. For example is value_a is 100 and the user enters 20 in the percent field, I would like the form to calculate that 20% of 100 is 20. I don't know java script but this seems like it would be easy but I can't figure it out.

Use this:

var Value_a = getField("Value_a").value;

var Percent = getField("percent").value;

var Percentage = percent / 100;

event.value = Value_a * Percentage;

var Value_a = getField("Value_a").value;

var Percent = getField("percent").value;

var Percentage = (percent / 100).value;

event.value = Value_a x Percentage;

This is what I am trying to do. The Percentage variable is not a field in my form. I am trying to get it to calcluate the percentage value because the user will enter 5 for 5% off. It give me this error: missing ; before statement 4: at line 5
