If you are lazy enough, why don't try the crashdetect plugin?
Use print("balbalba"); between functions will also help you debug the script.

Also, you don't need a sscanf for pure strings. Directly use "params" and isnull instead.
Last but not least, I guess the type in

pawn Код:

stock alphabetIndex(const input)

is incorrect. Shouldn't that be something like

pawn Код:

char:input

?

Didn't see the above post
