schema rule help

I need help in schema rule.

The requirement is such that if the gross salary is zero or less than than Wage type "A", then wage type "A" will not be deducted.

 /A Wage Type A
   ADDWT *    OT   Output table   
   ZERO= NR   AmtNumRteTime = 0   
   ELIMI *    Elim.time period ID 
   AMT=* /102 Set                 
 " AMT?0      Comparison          
     *                            
   " <                            
       AMT*0      Multiplication 

Appreciate fast reply. Thank you.
