hey thanx alot

...the combo boxes are working now

...
now u have seen two combo boxes
quantity to be issued (suppose m issuing 5 items of abc spare,,n actually i have 100 of them...i want when i issued this form n press OK...this Issued quantity shud b subtracted from 100..and 'Quantity' field in table T_db1 is updated by 95)
issued to group: its a text field of 3 to 6 letters only i.e ABC..
i want when i press OK button ..the current FORM5 data should be save in T_db2..and by clicking on button "REport"..it shud generate report of FORM5..
hey one more thing..let suppose i have only 1 spare and i issued that spare to user..so that spare shud be deleted from T_db1..so that if user search that spare...the msg shud be popup that "Record not found"
