Fill Userform Textboxes From Select Cells In Selected Range

Arised from my earlier posting in Populate ComboBox With Specific Sheet Column Range. I have the following working code below, but am having trouble finding coding examples to select specific cells from the selected row (that was found by selecting a ComboBox value)and update TextBoxes with those individual values after the UserForm has been initialized (the bold "GREEN" comment in the code below). I have been able to find plenty of references to update TextBox values to Cells, but that doesn't do me much good in this application since the User needs to verify the old data in these cells before updating them using the UserForm TextBoxes.

I was toying around with several different variations of code (none of which worked properly), so I left it out for clarity of my working code. I'll post up this non-working code as needed, because I really wanted a fresh answer...not what I was trying to do. The attached file should be sufficient to see what's going on

Private Sub UserForm_Initialize()
With Sheets("SR Information")
.Range("A2", .Cells(Rows.Count, "A").End(xlUp)).Name = "MyRange"
End With
SRnumber.RowSource = "MyRange"
End Sub

Private Sub SRnumber_Change()
Dim ServiceRequestNumber As String
Dim c As Range
Dim rngG As Range
Sheets("SR Information").Select
With Selection
ServiceRequestNumber = SRnumber.Value
For Each c In Intersect(ActiveSheet.UsedRange, Columns("a"))
If c = ServiceRequestNumber Then..................
