Integer - Wesley221 - 07.09.2011

How can i check if an integer is empty in this piece of code:

pawn Код:

if( !sscanf(params, "iii", vModel, vColor1, vColor2) )
        {
            if( !strlen(vModel) ) return SendClientMessage(playerid, -1, " ** You have to type the vehicle model in order to create a vehicle. ");
            if( !strlen(vColor1) ) return SendClientMessage(playerid, -1, " ** You have to type the vehicle color (1) in order to create a vehicle. ");
            if( !strlen(vColor2) ) return SendClientMessage(playerid, -1, " ** You have to type the vehicle color (2) in order to create a vehicle. "); 
        }

I tried it with strlen, but that gave me errors. Also i tried isnull, but that gave me errors aswell.

Код:

//strlen errors:
error 035: argument type mismatch (argument 1)
error 035: argument type mismatch (argument 1)
error 035: argument type mismatch (argument 1)

//isnull errors:
error 028: invalid subscript (not an array or too many subscripts): "vModel"
error 029: invalid expression, assumed zero
error 028: invalid subscript (not an array or too many subscripts): "vModel"
fatal error 107: too many error messages on one line
