copy information from one field to another automatically

[islandgirl23]

This is fairly a simple question.  I have a fillable form which requires you to enter the same amount in two fields. Is there a way to enter the amount in one field and have it automatically be entered into the other field?

Give both fields the same name.

Let me be a little more clear.  I only want to enter that amount one time.  On my form, I have to list gift cards separately on the form.  The remaining balances of each gift card has it's own field for each card listed.  The amount entered in the remaining balances field is also entered in a "value" field for each card.  All value fields are then totaled at the bottom of the form.  Instead of entering the balance in the remaining balance field and then tabbing over to the value field and entering it again, I want to enter it once in the remaining balance field and have that amount automatically get entered in the value field.  Both fields are text fields that are set as a number with a dollar sign.

Give both fields the same name.

But my total value field has a calculation in it.  If i make both fields the same name, it will count the entered amount twice.  I'm looking for some type of javascript.

No, it won't.

Anyway, if you don't want to give the fields the same name you can use this code (as the custom calculation script of the second field) to copy the value from the first (let's say it's called "Text1"):

event.value = this.getField("Text1").valueAsString;

That works!  Thank you
