I am trying to set up a validation method for a text box in Visual Basic
Editor. I need to validate the cell so that it is 11 digits long and only
contains numbers, if possible it must have a 0 at the beginning, though this
is not compulsory. This validation is for a telephone number, but i have not
found any way to validate the box apart from maximum text length. Any help
would be appreciated a lot, thanks.

Matt,

Try this

Private Sub TextBox1_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)
With TextBox1
If Len(.Text) = 11 Then
KeyAscii = 0
ElseIf Len(.Text) = 0 Then
If KeyAscii < 48 Then
KeyAscii = 0
End If
ElseIf Not IsNumeric(Asc(KeyAscii)) Then
KeyAscii = 0
End If
End With
End Sub
