Cobol: If statement is invalid?

I'm trying to do some data validation through a couple "If" statements, but I keep getting a Statement is invalid error and i'm not sure why..

       3100-ERROR-ROUTINE.
       MOVE "NO"                   TO ERROR-FLAG.
       IF RECORD-CODE IS NOT VC
           MOVE "YES"              TO ERROR-FLAG
           ADD 1 TO INVALID-RECORDS.
           MOVE "**" TO A-AST-OUT.
           MOVE "A"  TO A-ERROR-OUT.
       END-IF.        //error here
       IF VEND-NUM = SPACES OR VEND-NUM IS NOT NUMERIC
           MOVE "YES"              TO ERROR-FLAG.
           ADD 1 TO INVALID-RECORDS.
           MOVE "**" TO B-AST-OUT.
           MOVE "A"  TO B-ERROR-OUT.
       END-IF.    //error here
