I'm trying to create a menubar which will set the onaction property of
each item to the same function. The only difference between each
button will be the variable it passes into it (which needs to be which
worksheet to use). Here is my code below so you can see what I'm
trying to do. The line with the "*" is the one which has the compile
error. I know it's wrong but I'm not sure how to change it.

Sub CreateMenubar()
Dim iCtr As Integer
iCtr = 0
Dim CapNames As Variant
Dim MenuObject As CommandBarPopup
Dim ws As Worksheet

Call RemoveMenubar

CapNames = Array()
ReDim CapNames(Sheets.Count - 1)
For Each ws In Worksheets
CapNames(ws.Index - 1) = ws.Name
Next

Set MenuObject =
Application.CommandBars(1).Controls.Add(Type:=msoC ontrolPopup, _
Befo=11, Temporary:=True)
MenuObject.Caption = MenuBarName

For iCtr = LBound(CapNames) To UBound(CapNames)
With MenuObject.Controls.Add(Type:=msoControlButton)
*.OnAction = "'" & ThisWorkbook.Name & "'!" &
"DecisionTree(" & Sheets(CapNames(iCtr)) & ")"
.Caption = CapNames(iCtr)
End With
Next iCtr
End Sub

Sub DecisionTree(ws As Worksheet)

Application.ScreenUpdating = False

MsgBox ("Welcome to the " & StrConv(ws.Name, vbProperCase) & "
decision tree.")
Cells(ws.Columns(1).Find(What:="A", LookIn:=xlFormulas, LookAt _
:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext,
MatchCase:= _
False, SearchFormat:=False).Row, 2).Select
ws.Cells(2, 2).Select

Do While ActiveCell.Offset(0, 3) = ""
If MsgBox(ActiveCell.Value, vbYesNo) = vbYes Then
Cells(FindIt(1, ws), 2).Select
Else
Cells(FindIt(2, ws), 2).Select
End If
Loop

MsgBox (ActiveCell.Value)
Application.ScreenUpdating = True
End Sub

Any help is much appreciated. Thanks!
