Re: T5 Select Menu with Other Option

[George Christman]

Other than a few typos, code compiled and worked, however doesn't seem to be
solving the issue. I'll show you exactly what I'm doing, maybe I'm missing
something small. The value never seems to equal OTHER in your method. I
really appreciate everything thus far. Thanks !
