Ok...
I have created two new Modes of Sale
1. A new manager MOS that I have given web user access to that I can unlock with a source code on TNEW
2. A new member MOS that is connected to a web ranking and also has web user access on
Both of these MOS appear to be triggering when tested, but when I attempt to access a performance from the event calendar the error message below is thrown
I have checked:
I'm sure I'm missing something very simple, but I can't locate the missing piece in the help docs. Please help!
I just wanted to update this post with the solution. It was a very simple fix, as I suspected :) When I created the new MOS I did not select a default price type when I associated the price types with the MOS. I missed the little check box!
