I've been trying for too much time to create a new Function in PEP2 and add discrete codes for the function from [Link: remotecentral.com]

In PEP2 I can add a new function (TEST1) but cannot for the life of me cut and paste the HEX codes into PEP. I tried copying them to the notepad, then into PEP2, no success. I reviewed the instructions found in the FAQ's, but I must be missing something basic. I would greatly appreciate it if someone could help me through this basic problem. If I could find the remote I could LEARN the codes from this old remote, but cannot locate it - Pioneer CU-SX148.

Thanks in advance for your help.
