Paypal Rebrander Not working...

I'm trying to Rebrand the Email address in the Buy Now Button for Paypal. It will work Perfectly when I use the code Paypal gave me.

We'll use this as an example:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="John@msn.com">
<input type="hidden" name="item_name" value="Ebook">
<input type="hidden" name="amount" value="1.00">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="bn" value="PP-BuyNowBF">
<input type="image" src="https://www.paypal.com/en_US/i/btn/x-click-but5.gif" border="0" name="submit">
<img alt="" border="0" src="https://www.paypal.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form>

The Line I'm trying to edit of course is this one:

<input type="hidden" name="business" value="John@msn.com">

I change the value to an Activ variable by the name of "youremail" and it will look like this:

<input type="hidden" name="business" value="[={youremail}]">

Now, preprocessor is on, I've added the activ variable on my Compiler and made the rebrander. However, when i publish the ebook, use the rebrander to insert the new email address, it won't take and it will default to the paypal page. I'm not sure what i'm doing wrong.

I've set the type to HTML Fragment AND Text to convert to HTML and of course set it to rebrand, but neither settings have worked. I even placed a value on it and it won't take.

I've had no problems using Activ Variables in the past w/ say rebrandable Email like this:

<a href="mailto:[={yoursitetitle1}]">  Email me </a>

That takes just fine, but I just can't get the paypal one to rebrand properly. Please advise.
