Concatenate String And Variable

Hey all, hope this question isn't too newbiefied :D .

I have a database where I must run 10 tests depending on which product I have selected (from a drop box). Each product requires different tests (of the 10) and I am hiding the tests that I do not need after the product is selected. The way I have it set up right now is I have 10 different If statements...one for each test on the "On Change" event.

I have been trying to reduce this down to one If statement nested inside a while loop, but my visual basic isn't very good. I have named the Test buttons Test3- Test13, and want to increment just the number of the test. However, when I try to plug in my concatenated string, I have problems. My code is as follows:

Dim testcount As Integer
Dim testcheck as Boolean
Dim testnumber as String

testcount = 3

While (testcount < 14)

testnumber = "Test" & testcount
If Me.selectedproduct.Column(testcount) = True
Me.testnumber.Visible = True
Else:
Me.testnumber.visible = False
End If

testcount = testcount + 1
WEnd



Me.testnumber is obviously not an object on the Form...so I guess my real question is, how do I get visual basic to plugin the variable testnumber so that the code reads Me.Test3.Visible.

Any help would be appreciated.
