Find Cell Value Row Number & Use For Column Number

to update these values via a form in this sheet. I can find the correct row to be edited by entering a value from column A and B. The problem is if I want display the values of that row first and then change it. If I want to change row 10 data how can I bring back the value in ROW 3 AND THE COLUMN VALUE? The next step would be to do the actual update if I want to change ROW 10 to "Ooi" and a sales value of 200?

This is what I have done so far:


Dim myRows As Integer

With Sheets("Mrt")

'Retrieve history information for row
For myRows = 4 To 49
If comboxDay.Text = Range("A" & myRows).Value And textboxdescription.Text = Range("B" & myRows).Value Then
textboxbedrag.Text = Range("C" & myRows).Value
chkBTW_Ja.Value = Range("D" & myRows).Value
txtNota.Text = Range("S" & myRows).Value
End If
Next
End With
