paypal information pass-thru

Have paypal standard. Just finished speaking with them because the notification of order that I receive from them does not contain variables within the order (ie. style choice nor engraving details).

These are both options that I have added to my ecart.

I have an email from Paypal showing the code passthrough. The 2 fields I am talking about pass through no value.

here is the first section of that code:

business=barkmail%40nitrodog.com&

amount_1=15&

item_name_1=small+enamel+ID+tag&

item_number_1=90088&

quantity_1=1&

on0_1=&

os0_1=&

on1_1=&

os1_1=&

handling_cart=0&

tax_cart=0&

I need this information to pass through to Paypal so I can properly process the order.

I am adding the style selection list in the properties management area.
The customer adds in the engraving detail in the text area provided.

I attached the page with those test buttons on it in case they are structured wrong.

Thank you.
