Open query using parameters in MS Access

Open query using parameters in MS Access

(OP)
Hi all,

I'm a Control Systems Engineer with not much experience in database programming, but I am trying to create an application using MS Access. I realize I may make a fool of myself asking this question, but I'll just have to risk it.

My database has several tables. The first table contains the panel numbers:

ID | Panel number |  Description
-------------------------------------
1  |    P-001      |  Control panel
2  |    P-002      |  Network panel
3  |    P-003       |  Remote I/O panel


The second table contains an overview of materials:

ID | Description
------------------------
1  | Enclosure
2  | Terminals block
3  | Cable gland


In a third table I keep track of the amount of materials per panel:

ID | Panel ID  |  Material ID  |  Qty
----------------------------------------
1  |     1     |       1       |   1
2  |     1     |       2       |   40
3  |     1     |       3       |   6
4  |     2     |       1       |   1
5  |     2     |       3       |   7
6  |     3     |       1       |   1
7  |     3     |       2       |   25


I have created a form to show the panel list (i.e. the first table), and want to add a button to this form that will show the materials in the selected panel.
I have already created a query that shows the panel name, material description and quantity for all panels, but I want the query to only show the data of the currently selected table. I know I can open the query with a parameter, but would like to know how I can automatically use the "panel ID" as the parameter?

Thanks for your help.
Caspar
