Linking two Combo Boxes

[ram_Sathish]

Hi all,

I have linked two combo boxes called center number and investigator name.

If I hit a number 1 in the combo box called center number then it has to show me the Investigators who are belongs to that center, it should not show me the other Investigators. I got my answer.

But i want it should be more user friendly.

Because i have linked the second combo box by a query.

While entry the query ask to enter the parameter value. It is not taking the value which is already available in the combo box called center number. The operator has to reenter the center name once again.

How to solve this problem.

Anyone please help me.

Thanks in advance.

Use the value from the 1st combobox as the parameter for the query.

If you look in help you'll see how to do that.

Ram, there are 2 steps:

1. Investigators combo:
Rowsource is something like
SELECT * FROM tblInvestigators WHERE CallCentre = Forms![MyForm]!CallCentre

2. In the AfterUpdate event of CallCentre:
Investigators.Requery

The first step links combo 2 to combo 1
The second step forces combo 2 to refresh once you select from combo 1
