Q:

Integrating PayPal buttons into site

I am trying to integrate PayPal buttons to a website.  It was a really tough job making such a big number of buttons but I some how did it, but now I see that some of them work while some of them do not(and go to PayPal's homepage.)  I am unable to determine what would have gone wrong which has caused this error.  
The code was very big to fit in here so I am sharing to forms, the first one works while the second does not. 
 <form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="business" value="xxxxx">
<input type="hidden" name="lc" value="US">
<input type="hidden" name="item_name" value="Sumission Order 1- 3 articles ">
<input type="hidden" name="amount" value="xxx">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="button_subtype" value="products">
<input type="hidden" name="no_note" value="0">
<input type="hidden" name="tax_rate" value="0.000">
<input type="hidden" name="shipping" value="0.00">
<input type="hidden" name="add" value="1">
<input type="hidden" name="bn" value="PP-ShopCartBF:btn_cart_LG.gif:NonHostedGuest">
<input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_cart_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!" >

</form>

Please help me out.  Thanks

A:

You have changed the names of the inputfields in the second form.  These are the variables that are send to PayPal.  This means you are now posting other variables; PayPal does not understand cmd2 for example, but it understands cmd.  So rename the inputfields inside the second form to cmd, business, lc, item_name .. etc and it should work. 
BTW It is not illegal to have duplicate names in html-tags, only duplicate ID's are not allowed.   
Success!
