warning 203: symbol is never used: "CivPedsMale"

means that you Have Defined CivPedsFemale And CivPedsMale
And you never Used Them
ON The Top of your script Search For
New CivPedsFemale;
New CivPedsmale;
And delete Them

Rename that "string" to something else because it's used somewhere else in your script.
Rename it to "string2" or whatever.

And don't forget to rename it everywhere it's used in that command. (format, SendNearbyMessage, ..., ...)
