<form name="_xclick" action="https://www.paypal.com/cgi-bin/webscr" method="post">

    <input type="hidden" name="cmd" value="_xclick">

    <input type="hidden" name="business" value="<?=$pay_email;?>">

    <input type="hidden" name="item_name" value="<?=$itm_name;?>">

    <input type="hidden" name="item_number" value="<?=$itm_no;?>">

    <input type="hidden" name="amount" value="<?=$pp_price;?>">

    <input type="hidden" name="custom" value="<? echo $custom_id; ?>">

    <input type="hidden" name="no_note" value="1">

    <input type="hidden" name="currency_code" value="<?=$pp_cur;?>">

    <input type="hidden" name="return" value="http://www.mysite.com/events/pplreturn.php">

      <input type="hidden" name="rm" value="2">

    <input type="hidden" name="cbt" value="Return to <?=$site_name; ?>">

</form>

So I am not understanding the why my customer or Paypal is sending this mail . Please help me to solve this issue . This is so urgent for me very soon.

Is it possible that we have to put in an IPN? But how ? and where I can put this ??
Please help me.
Thanks,
Kparas

IPN with PayPal is not as hard as it sounds...There's a great PHP library out there that supports it with reasonable docs: Micah Carrick's Paypal Class. I put this on my site and the IPN code is pretty straightforward, but you may want to read the PayPal documentation about the returned data as background.

Thanks for reply,

I have seen which link you given. But i did not get answer or solution in my code. Please help me . I am new in Paypal integration. I did not find solution for that. Please help me to solve this exactly. Where i will have to change in my paypal code which is given above.

I need it very soon.

Thanks

It will be quicker for you to use the paypal class than to figure out what is wrong with your code.

If you had provided all of the code set up to use the PayPal sandbox then it would be easy to take that code and duplicate the error. What you have provided isn't sufficient to do that. There is definitely more that you need to make IPN work so I assume that you have other code that you haven't provided.
