Print transactions in Customer Center with Suite Promotion

Can you please with my formula? I am trying to have the customers print their transactions from the customer center since they cannot view them with the Suite Promotion.

I am unable to print any packing slip from the item fulfillment record. Is it a formula issue? Anyone has a better solution?

Regards,
