Copy Contents Of Worksheet Textbox To Another

I have a multiple sheet workbook designed to collect information which is all collated on the last sheet. On one sheet I have a textbox (not the drawing textbox) which is designed to take a string of characters of a specific lenght (150chars) and works well. I'm just trying to get the code to work with a textbox on the same sheet for now, then when its working change it to copy over to another sheet.

Sub TextBox_To_TextBox()
Dim x As Integer
Dim PreEmp As TextBox, PreEmp2 As TextBox
Dim theText As String
Set PreEmp = ActiveSheet.TextBoxes("PreEmp")
Set PreEmp2 = ActiveSheet.TextBoxes("PreEmp2")
For x = 1 To PreEmp.Characters.Count Step 150
theText = PreEmp.Characters(Start:=x, Length:=150).Text
PreEmp2.Characters(Start:=x, Length:=150).Text = theText
Next
End Sub

I'm calling the sub routine but nothing seems to happen.
