Adding PayPal code to Flash button

Question

I want to use my own .swf button for PayPal payments with a "hidden format", but when adding the generated PayPal Website code to my html page, only a red X and the alt PayPal text is showing where the button should be. I have changed all Active X controls to Enable.
Every time I contact PayPal I get a different reply. The last one was that I have to add a "static" image, but I really want to use my own button.
I would rather find a way to paste the PayPal code into my buttons action script and then I only have to paste the Flash button to the html, but don't know how to manipulate that because the only code generated by PayPal is a "form" in html format. I am also adding text fields and guess that's why I don't get an generated email code from PayPal which I get if I don't add text fields.
Any ideas how I can transform the code generated by PayPal to my action script are welcomed. I have about 150 buttons to add!

I will definitely mark when I have managed to do this, thank you. Still can't get it to work and I don't know where I'm going wrong, but shall continue trying...
I have added the form in my html, but deleted the button which appeared as an X. Instead I've added my button with the code you gave me in AS.
I don't know what I am doing wrong, but I keep receiving action script error messages:
