Bug in Edit Route page (edit_route.php)

[Calebrw]

Got another bug for you guys.

I accidentally added a plus sign (+) behind my route number to make it "029+" instead of "029".

This produced the following error message:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /var/www/vhosts/airlinemogul.com/httpdocs/airlinemogul/includes/cr_functions.php on line 889
0

I'll leave it be for now so you guys can review, but this error can be found in the following:
Airline ID: 27386
World ID: 818
Route ID: 3608

I don't know that the actual error message can be prevented, but I figure that the input can be checked for proper format (numbers in this case).

The box usually does remove non-numbers, and everything after it (i.e. 16^3 goes to 16). I am guessing, but the + sign may not be filtered out when dealing with numbers so that there can be a distinction between positive and negative numbers.

I just tested it out, and it appeared to work fine, trying + before, in the middle and after.
