[Excel 2003]

I have a user form with text boxes.

I populate the text boxes using the following type of code:

Private Sub CommandSheet1Get_Click()
Dim ws As Worksheet
Set ws = Worksheets("Sheet1")
Me.txtname.Value = ws.Range("A1").Value
End Sub

I can edit the text boxes and then update the spreadsheet with the following
code in another command button

Private Sub cmdSendtoSheet1_Click()
Dim ws As Worksheet
Set ws = Worksheets("Sheet1")
ws.Range("A1").Value = Me.txtname.Value
End Sub

Using this approach I can use a number of command buttons to pull data to
the text boxes from different sheets 1,2,3....10. However, here is my
question/problem.

Although I want to have separate buttons for pulling the data to the
textboxes, I want to use just a single button for sending the edited data
back to the sheets.

So what I would need is for the code to keep track of which sheet the data
came from and when the button is pressed, would access the suitable
subroutine to return the data to the right sheet

To put things in perspective I have approx 300 cells on each sheet to deal
with. The same cells on each sheet are used for storing the data I work with.

Can anyone help?
