Mr. Litch, It worked! Thank you. .........although, I have 190 textboxes in the userform. Am I assuming correct when I assume the following code must be repeated (with edited textbox id# identified), 190 times?

Private Sub UserForm_Initialize()
UpDateFlag = False
Me.TextBox01.Text = Range("E19").Value
UpDateFlag = True
End Sub
Private Sub TextBox01_Change()
If UpDateFlag = False Then Exit Sub
Range("E19").Value = Me.TextBox01.Text
End Sub

If so, perhaps you may know of a global solution? If not - I am still very appreciative as you have provided something of great value!
