I would like to be able to send an invoice when the Invoice radio button is selected. The form I'm using will collect a registration payment when the Pay Now option is selected, but can I make it send an invoice if the Invoice option is selected?

I know I can send an auto response message and can customize that email as necessary, but can it only send it when the Invoice option is selected on the form? I don't see a way to customize it to send a different message depending on what is selected on the form.

I thought about just designing the auto response message so it showed as an Invoice / Receipt, but I'm not sure how to make it show that the registration was either paid or an invoice was requested. That would probably work if someone can give me a hint of how to do that.

Second question: Can I disable an option button after a certain date? After August 1st, the registration fee changes.

This is the link to my form (hosted on S-drive):

Note: I have it set for just $1 for registration while I test it, but I recommend that you don't click on Submit (unless you don't mind sending me $1 - ... )

You'll have to make your own custom script to replace the myfromname.php.
