Hi,

I need help with calculation.
Text1 have value 5/100

Text 2 have value 100

Text 3 is product of Text1 and Text2.

when I use simple product, it comes 510 as result.
when I use below script, it comes NAN.

var a = Number(this.getField("Text1").valueAsString);
var b = this.getField("Text2").value;

event.value = a*b;

I want to achieve 5 as result. I hope someone will help me. PDF is attached for reference.

Thanks!

You can't calculate like that.

Also you set text2 to be same as text1 so text2 is not 100 it's also 5/100.

Can you describe what you try to achive?

Why do you enter value as 5/100, why not use 5 and divide by 100 in script or just use result value of 0.05 since you already know what it is?

I can't use 5 and divide by 100. It can be any number it can 3/100 or just 3. So I want field 1 will work like below condition.

If I write 5/100 in that field it multiply/divide other field with 0.05.

If I write 3/100 in that field it multiply/divide other field with 0.03.

If I write 5 in that field it multiply/divide other field with 5.

5/100 is a actually the JavaScript code for 5 divided by 100. So one way to achieve the result you want is to execute the entered text as if it was JavaScript.

event.value = exec(this.getField("Text1").value) * this.getField("Text2").value;

of course. If the value of "Text1" is not executable JavaScript code there will be an error. So you'll either have to guarentee that condition, or add some error handling to the calculation script.
