looping with variable control name

I have this code:

VB Code:

For i = 1 To 4
    For j = 0 To 4
        SQLSTR = "INSERT INTO Coeff (CAL_ID, Curve_Order, Coeff, Coeff_Val) VALUES (" & CALID & ", " & i & ", " & j & ", " & frmRegression.txtCoefficient_ & i & (j) & ")"
        CN.Execute (SQLSTR)
    Next j
Next i

And what I'm trying to do is loop through sets of control arrays to store some variables. It's the following line that I have a problem with:

frmRegression.txtCoefficient_ & i & (j)

I need a way to make it look for that control array and then get that value from that control array. I know there has to be an easy way to do this.

What exactly is the name of your control array and their indexes?

You will need to use the Form's Controls collection.
Try the following

frmRegression.Controls("txtCoefficient_" & i)(j).Text
