Need help with Authorize.net widget.

I have selected Payment Type to User Defined Amount. But then the next field called "Get Price From" is not showing me any options to select from. I have already setup a field (Number) as a placeholder for the amount that I proposed to pass via custom url. I was going to have a "pre-filled" link sent out to the customer so that the form would have the amount already set.

nevermind. I figured out a work around.
