combox box and shared variable


Recommended Posts

i'm controlling data that enter to a table by using a combo box specific,let's call it "NR ORDRE", when a client has the num 5 and enters his data ;it will be stocked in the 5th row.i want this number 5 to be removed from the list ,so when a new user try to enter num 5 he gets a message"number already used" or he doesn't find number 5 in th combo box ,so he have to enter a different number than 5,for instance 8,consequently i'll get all his data in the 8th row.

 i'll need something to remove a number from a combo box when it's already used by a client >> unique number for each client

 

if anyone know a little trick to solve this problem

thanks
