Ahoy all! So I will start by saying I am brand new to javascript and am learning things the hard way! 🙂

I am trying to figure out a way that I can have two text fields, Field1 & Field2, and have it so that when a number is entered into Field2 it will automatically add it to Field1 then clear itself out.

Example: Field1 has a value of 10, when I enter 10 into Field2 then Field1 become 20 and Field2 becomes blank. I am figuring the javascript will have to be attached to a button but my co-pilot, google, is letting me down on this one. Any ideas? Thank you!

The script doesn't have to be on a button, unless that's what you want.

But here is a button script.

this.getField("Field1").value += Number(this.getField("Field2").value);

this.getField("Field2").value = "";

Field 1 needs to be defaulted to 0

That worked perfectly! Thank you so much!

Would it be possible to multiple the value of Field2 by -1 to convert it to a negative value?
