I have a userform that allows a person to type info into some textboxes and
then they can press a button and enter the data onto a worksheet. I want to
be able to check a column for one of the numbers entered to make sure there
are no duplicates. If they try to enter the same number twice i want a
message box to come up explaining what the problem is.

enyaw,

There is a message box asking you if you wish to stop there or keep
searching, change that to whatever action you wish to take when a
duplicate is found.

Dim oCell As Range
Dim wks As Worksheet
Dim strAddress As String
Dim FindWhat As String
Dim hawb As String
Sheets("sheet1").Select
hawb = Textbox1.Value
FindWhat = hawb
If FindWhat <= "" Then
Exit Sub
Else
For Each wks In Worksheets
'Find first occurrence in sheet
With wks.Cells
Set oCell = .Find(What:=FindWhat, LookIn:=xlFormulas, _
LookAt:=xlPart, SearchOrder:=xlByRows, _
SearchDirection:=xlNext, _
MatchCase:=False)
If oCell Is Nothing Then
MsgBox "Not Found on: " & .Parent.Name
Sheets("sheet1").Select
Else
strAddress = oCell.Address(External:=True)
Do
Application.GoTo oCell, Scroll:=True
If MsgBox("Stop Here?", vbYesNo, "Found at cell
" _
& oCell.Address(External:=True)) = vbYes
Then
Application.GoTo oCell
Sheets("sheet1").Select
Exit Sub
Else
Set oCell = .FindNext(oCell)
Sheets("sheet1").Select
End If
Loop Until oCell.Address(External:=True) = strAddress
End If
End With
Next wks


Hope this helps

Duncan
