Run Time Error 340

[WildSilver6]

Ok so I'm trying one of the tutorials called Mailsystem / Character Sheet (its in the Tutorial Section on the wbsite) and so I put the code in and made one modification. Instead of it saying GetPlayerSex I changed it to GetPlayerGender. (only thing i did). So anyway I run my client and try to hit the Page Up button and all of a sudden I get a RTE:

Run-time Error '340'
Control array element '12' doesn't exist

Any tips?

I get the same error, doing the same thing.

I know the error, but not the fix; it seems to activate when you run a custom menu, then a custom menu with higher index numbers. At least that's how it happens with me.

What happens with me is whenever I change some of the scripts to the tutorial I get different Errors. For example the 12 can sometimes change to 3 or 8\. So it must have something to do with the scripts too.
