The button should already be linked assuming you used the online button creator to generate the code. Most likely the problem is either with your web page, site host or how your HTML Editor handled inserting the code. We could better help you out if you provide a link to the web page that has the code. Per your description, it sounds like you have a "nested" form issue where as you have a form within a form. (The PayPal item button code is basically an HTML Form.)
Here's an update to what was posted above.
I looked at your web page:
http://www.shenvalleysoccer.com/Default.aspx?tabid=279050
You're using Add to Cart code, not that it really matters however, you do have a "nested" form issue where as you have a Form within a Form.
I found this line of code:
<form name="Form" method="post" action="/Default.aspx?tabid=279050" id="Form" enctype="multipart/form-data">
The problem is there is no "closing" or "ending" form tag or something that looks like this: </form>.
This situation confuses the web browser, it sees the start of a form but does not find the end of the form until it reaches your PayPal Add to Cart item button. As the PayPal item button has the closing </form> tag, the browser thinks the first form is complete which in turn causes the PayPal code to not function.
The PayPal item button code works perfectly fine by itself and does take you to your PayPal SVU checkout page. I tested that code with a blank web page, works great.
What you need to do is place the ending </form> tag for the first form where it's needed. Then both of your forms will work properly. Else rem out that line of code if it's not used.
