I was working on the Upstate Building Industry Alliance website and had to put a couple PayPal buttons in. If found that after I pasted the code in while in the TEXT view changing to VISUAL and back would strip the Form tags and other code from the button.
After a bunch of trying this and that I found that putting the button code in a TABLE worked. Here’s an example:
<table><tr><td>Quarterly Subscription<br/>is $73.75 per quarter</td></tr><tr><td>PASTE YOUR BUTTON CODE FROM PAYPAL HERE</td></tr></table>
When you put this in you should be in the TEXT view. You can try adjusting the table layout with style and such BUT – I always do a CTRL A, CTRL C before I leave the text view – just in case.
