Form action code getting stripped out

Hello all!
I am running CB 1.4 on Joomla 1.6.4 and I have ran into a problem.
I've create a field of type text editor for the purposes of pasting Paypal button code to the user's profile. I am using TinyMCE as the editor but it doesn't matter if I use straight text box, the following always gets stripped out of the code when I click the "Update" button when editing the field on my profile:
action=" www.paypal.com/cgi-bin/webscr "

Obviously this prevents the button from working. I have verified I can use this button in Joomla.
I should be able to use this code without and for-pay plugins, correct?
Thanks for any help!!

Surely someone else has ran into this?

CB Configuration area has parameter to specify which tags should not be stripped.

But for such a case you should really use a delimiter field.

Thanks for the response nant.

I have added action tag to the parameters list yet it still gets yanked so I thought there was something hard-coded. Maybe I just put it in wrong.
The delimeter field works great BUT the paypal button code is unique to every member so a delimeter field wouldn't work in this scenario, correct?
Obviously if there is a better way to achieve this I am all for it!

I appreciate your time and help.

how is it unique?

It is unique in the sense that the button links back to that user's paypal account.
What my intention is, is that vistors to that user's profile can click on the paypal button to pay for whatever that user is selling. So each user needs a PayPal account and then has to create the button which generates the code. Then they need to paste that code into their CB profile. Even if the user couldn't do it and it would require an admin to place the code into their profile, that would be okay.
