You're returning values straight after the (if) statement.
Doing this:

pawn Код:

if(!(3 <= strlen(inputtext) <= 20)) return SendClientMessage(playerid, RED, "The password you supplied is either too short or too long.");

Will return the Client Message, and nothing else. You're stopping the function at that point. That means anything that's written later on will be ignored.

The correct method:

pawn Код:

if(!(3 <= strlen(inputtext) <= 20))
{
     // code...
     return whatever;

}
