Is there any reason why my function would say my variable is "not declared" even when it's clearly in the script? If I try to save the following script it states just that for 'maxweek1':

2. void schedule_teams.mhl_scheduling_module.toString()
3. {
4.     for each r in MHL_Scheduling_Module  [(Season == "Winter 2013" && (Team_1 is null))] sort by  Team_1 
5.     {
6.         scheduleteam15  =  MHL_Team_Contact_Info_Entry  [((((Current_Last_Season_New == r.Season && Nights_Playing == r.Day) && Team_Name != "(Non-League Opponent)") && Team_Name != "(TBA)") && Rinks_Playing == r.Rink)];
7.         r.Team_1 = scheduleteam15.Team_Name;
8.         r.Team_1_Level = scheduleteam15.Level;
9.         r.Team_1_Div = scheduleteam15.Division;
10.         r.Team_1_Bal_Remain = scheduleteam15.Bal_Remain;
11.         r.Team_1_Pct_Paid = scheduleteam15.Pct_Paid;
12.         maxweek1 = MHL_Scheduling_Module[(r.Team_1 == r.Team_1 && r.Week == r.Week)].count();
13.         if (maxweek1  >  1)
14.         {
15. r.Team_1 = maxweek1.Team_1;
16.         }
17.     }
18. }

Any ideas on why this is happening?
