Each week I feature one of my answers on stackoverflow hoping it might help other people.

The question

This weeks question by Wazzy: PayPal with IPN enabled invoking error on cmd = “_cart”

I am using PayPal Website Payment Standard with IPN enabled.

Before I was setting cmd variable like this

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

but then I canged it to

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

Also I changed some other variables inside my form

<input type="hidden" name="item_name_1" value="Item1">
<input type="hidden" name="amount_1" value="2">
<input type="hidden" name="item_name_2" value="Item2">
<input type="hidden" name="amount_2" value="2">
<input type="hidden" name="quantity_1" value="1">
<input type="hidden" name="quantity_2" value="2">
<input type="hidden" name="item_number_1" value="121">
<input type="hidden" name="item_number_2" value="122">

But when the form is Posted to PayPal I am getting this error.

My anwser
