I meant to the value inside of the text box. In your example, do something like:
AutomationLetterWordDemo.txtCustomerName.Text = Chr(34) & AutomationLetterWordDemo.txtCustomerName.Text & Chr(34)

Where Chr(34) is the double quote character.

But, if you just need to have a variable field name from the recordset just play with the actual field name and put that in the variable:
myField = "ReplaceFieldName"
y = Rs.Fields(myField).Value
