Please correct the store procedure routine

1.  @ZBACK is the number of times the routine will run

2.  @ZIDNO and   @ZLOANUMBER   is the particular record which is      

    selected from the 2 linked tables a. LOANS and b. INTEREST

Can you please provide a better way to perform the undernoted routine
