error 021: symbol already defined: "JobTimer"

This code means that you have defined it somewhere else on the very top of your script and you forgot like"

pawn Код:

new JobTimer[MAX_PLAYERS];
/* line 25{code}
line 300*{other pieces of code}*/
new JobTimer[MAX_PLAYERS];

And you cannot notice you defined it twice,because of too many lines between the definitions,so just try to remove it,and see if it fixes the errors.
