With Selection Input Cell Value or Range into User Form

Hi all,

I'm trying to setup some code that, if a user selects a specific cell then that cell value will
be inputed into a user form. I tried reversing some code that I have that adds a users
cell range selection to cell, but something is still not right.

Here's what I have thus far:

 Dim Raddress As Range, strAddress As String
 With Selection
 Set Raddress = Cells(17, 3).Value
 UserForm1.RefEdit1.Text = Raddress.Address 'Allow cell selection to be placed into user form
 Raddress.Address = UserForm1.RefEdit1.Text 'Allow changes to the range be made also in  the userform field.
 
 End Select
  ' Set Raddress = Application.InputBox("Select your range to print by placing your mouse pointer over a starting cell box. Left click and hold while moving your pointer to the last desired cell. Then choose OK to Print or Cancel to Stop.", Type:=8)
     '17 = Rows  ,15= Columns
    'Raddress = Raddress.Address
Set Raddress = Range(Cells(17, 3).Value) '17 = Rows  ,3= Columns C' Places last entered value in userform field back into selected cell.

Any help is appreciated.
Thanks,
