Hi,
ouch....
Please don't do that, if you want to stay sane

use Arrays, use ArrayMaker, but don't hardcode global variables this way, this clearly needs heavy refactoring.
Let me know what you are trying to achieve with these global variables, and I'll propose some other approaches.
now to optimize the drop down, always create your variables with / char, it will automatically create a drop down sub menu.

the same is true for event names.
Bye,
Jean
