So you want a form:
[tt]
? Product 1 ? Product 2 ? Product 3
? Product 4 ? Product 5 ? Product 6
? Product 7 ? Product 8 ? Product 9[/tt]
when the user selects the check box next to Product 1 you want to open another form:
How many? _____
[OK] [Cancel]
When they press OK, you want to write a record to a table storing this information.
Do you have "customers" that order these products? Do you not need to know which customer ordered it?
What if someone wants to order 2 things? Does the user have to do this twice?
Why not have a "SALE" form that has a subform that allows the user to select a product from a drop down and enter the number of items.
Then if the user needs to add another product to the Sale, they just move to the next line and select the other product.
Did you look at the Northwind samples like I suggested?
