Sequential Time Ticket Number Generator on Print won't increment

Hello all,

I have a VBA project that I took a solution from that I can't get to work. There may be a portion of the Print number sequence generator that is not running. It won't increment after print. After revising the original cell reference I can successfully set the Time Ticket number with F5. This VBA routine is from an old thread called Sequential PO# but renamed the Set PO to Set TimeTicketNo in my VBA subroutine. It won't run with F5 and will try to pop up an overlay for selecting a MACRO and run or create which is confusing me considerably. I've played with VBA just a little and I'm just starting to grasp some of the syntax but obviously not enough to correct this. I would think there would be something in the text that would have a print reference but I don't see it. Maybe that's the problem but I don't know how to write it out and insert it in proper location. Any help from the gurus here would be appreciated. I've attached the workbook I'm testing this with. I've copied and pasted and wrapped the original thread below. I hope this is correct method.
