Thats correct. I included it in with TextBox36 as follows:

Private Sub TextBox36_BeforeUpdate(ByVal Cancel As MSForms.ReturnBoolean)
TextBox36.Value = Format(TextBox36.Value, "dd-mmm-yy")
If IsDate(Me.TextBox36.Value) Then
Me.TextBox37.Value _
= Format(CDate(Me.TextBox36.Value) + 90, "dd-mmm-yy")
Me.TextBox38.Value _
= Format(CDate(Me.TextBox36.Value) + 120, "dd-mmm-yy")
Else
Beep
Cancel = True
End If
End Sub

The code (cut down) looks like this:

Private Sub CommandButton1_Click()
Dim LastRow As Range
Dim iRow As Long
Dim FirstRow As Long
Dim LastRowNumber As Long
Dim wks As Worksheet
Application.DisplayAlerts = False
Application.EnableEvents = False

Set LastRow = Sheet2.Range("a100").End(xlUp)
LastRow.Offset(1, 48).Value = TextBox36.Text
LastRow.Offset(1, 49).Value = TextBox37.Text
LastRow.Offset(1, 50).Value = TextBox38.Text
MsgBox ("Data has been entered")
For Each wks In Worksheets(Array("customers"))
With wks
FirstRow = 2 'headers in row 1
'Changed LastRow to LastRowNumber
'Dim LastRowNumber as Long added above
'LastRow is declared as Range
'We need it to be Long
LastRowNumber = .Cells(.Rows.Count, "A").End(xlUp).Row

For iRow = FirstRow To LastRowNumber Step 1
If Application.CountIf(.Range("a2").EntireColumn, _
.Cells(iRow, "A").Value) 1 Then
'it's a duplicate
MsgBox .Cells(iRow, "A").Value
.Rows(iRow).Delete
End If
Next iRow
End With
Next wks
Application.EnableEvents = True
Application.DisplayAlerts = True
End Sub

Private Sub CommandButton2_Click()
'Search button
Dim FoundCell As Range
Application.DisplayAlerts = False
Application.EnableEvents = False

If Me.ComboBox1.ListIndex = -1 Then
'nothing filled in
Beep
Exit Sub
End If
With Worksheets("customers").Range("A:A")
Set FoundCell = .Cells.Find(what:=Me.ComboBox1.Value, _
After:=.Cells(1), _
LookIn:=xlValues, _
lookat:=xlWhole, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, _
MatchCase:=False)
End With
If FoundCell Is Nothing Then
'this shouldn't happen!
Beep
Else
Me.TextBox1.Value = FoundCell.Offset(0, 0).Value
Me.TextBox3.Value = FoundCell.Offset(0, 2).Value
If IsDate(FoundCell.Offset(0, 1).Value) Then
Me.TextBox36.Value = Format(FoundCell.Offset(0, 48).Value, "dd-mmm-yy")
Me.TextBox37.Value = Format(FoundCell.Offset(0, 49).Value, "dd-mmm-yy")
Me.TextBox38.Value = Format(FoundCell.Offset(0, 50).Value, "dd-mmm-yy")
Else
Me.TextBox36.Value = ""
Me.TextBox37.Value = ""
Me.TextBox38.Value = ""
End If


Application.EnableEvents = True
Application.DisplayAlerts = True

End Sub

Private Sub TextBox36_BeforeUpdate(ByVal Cancel As MSForms.ReturnBoolean)
TextBox36.Value = Format(TextBox36.Value, "dd-mmm-yy")
If IsDate(Me.TextBox36.Value) Then
Me.TextBox37.Value _
= Format(CDate(Me.TextBox36.Value) + 90, "dd-mmm-yy")
Me.TextBox38.Value _
= Format(CDate(Me.TextBox36.Value) + 120, "dd-mmm-yy")
Else
Beep
Cancel = True
End If
End Sub

Obviously there are alot more textboxes but that is the general outline of
the code.

Does that mean that neither TextBox37 or 38 have their own event code?

The codes I have are as follows:

To insert the dates in data sheet:

LastRow.Offset(1, 48).Value = TextBox36.Text
LastRow.Offset(1, 49).Value = TextBox37.Text
LastRow.Offset(1, 50).Value = TextBox38.Text

To look up data from data sheet:

Me.TextBox36.Value = Format(FoundCell.Offset(0, 48).Value, "dd-mmm-yy")
Me.TextBox37.Value = Format(FoundCell.Offset(0, 49).Value, "dd-mmm-yy")
Me.TextBox38.Value = Format(FoundCell.Offset(0, 50).Value, "dd-mmm-yy")

Else
Me.TextBox36.Value = ""
Me.TextBox37.Value = ""
Me.TextBox38.Value = ""

If you need more of the code let me know.
Thank you

THi,
I have a Textbox when entered a date, it adds 90 days and 120 days to
that
date and enteres these dates to two more textboxes.
The trouble I am having is when a date is entered in error in the first
Textbox I can not clear it. The cursor freezes. Any ideas?
The code I am using is as follows:

Private Sub TextBox36_BeforeUpdate(ByVal Cancel As
MSForms.ReturnBoolean)
TextBox36.Value = Format(TextBox36.Value, "dd-mmm-yy")
If IsDate(Me.TextBox36.Value) Then
Me.TextBox37.Value _
= Format(CDate(Me.TextBox36.Value) + 90, "dd-mmm-yy")
Me.TextBox38.Value _
= Format(CDate(Me.TextBox36.Value) + 120, "dd-mmm-yy")
Else
Beep
Cancel = True
End If
End Sub
