I tried your example using your code and it worked fine. When I used the following code, it didn't work

Dim oSC As ScriptControl
Set oSC = New ScriptControl
oSC.Language = "VBScript"

Dim y As String
y = "AutomationLetterWordDemo.txtCustomerName.Text"
y = oSC.Eval(y)
Debug.Print oSC.Eval(y)

The string represented by y is a valid Form Text Control and contains a value of "Dan

But when I execute "y = oSC.Eval(y)", the value of y is still "AutomationLetterWordDemo.txtCustomerName.Text"

Tis a puzzle to me...
