perl script modification

I have a simple cart perl script duplicated three times to serve different products, installed on site. I have moved the site from a shared server to a cloud server and the scripts are throwing up an error. They worked 100% on the shared server. I understand from the server tech that it is a simple job to modify the scripts to get them working. I need someone with perl expertise to troubleshoot the scripts and get them working fully. I can supply FTP access, etc. The scripts in question are here: [login to view URL] [login to view URL] And are accessed via the web page here: [login to view URL] You can order on-line and pay with your credit/debit card by using our Senior Polo Order Form here [login to view URL] You can order on-line and pay with your credit/debit card by using our SUPA/Ponyclub Order Form here [login to view URL]
