Sub With Argument Using External Values

There are 100 loans, each one of them need to be tested on 11 different tests, the results are either "pass" or "fail". All the test results are stored in the Boolean array. g_sel_tag(). For instance, if g_sel_tag(2,7) = true that means the 2nd loan has failed on the 7th test.

But I got stock with the following code, I think there should be a loop for the public variable rep_num in order to loop through the 11 test results for each loan. I have searched the entire project but did not find any value was assigned to the variable rep_num. The following code is part of a huge project, I can't test run it to see if the following code is valid at this point.

I am new to VBA therefore wondering if it is valid with no specific value assigned to rep_num. (I think there should be something like "for rep_num = 1 to 11" in order to get it running).

There are several codes in the project with similar structure where they just use rep_num without assigning any specific values.

Code:
Dim rep_num As Interger
Sub test_results_reporter (rep_num As Interger)
Dim i As Interger
Dim g_sel_tag(1 to 100, 1 to 11) as Boolean
For i = 1 to 100
If g_sel_tag(i,rep_num) Then Msgbox "Loan" & i & "has failed on test" & rep_num
Next
End sub
