If Else Syntax: Change Some Outputs Of The Macro Without Changing The Syntax

I´m writting a macro. It works find until a certain point. When I want to change some outputs of the macro without changing the syntax, it display an error mesage while runing the macro. It says Else without If. Which is quite disturbing because the Else was not creating any problem before. Here is my macro before I changed the conditions (this one work nicely)

Sub Copy_Sheet_Beta()
Set wba = ActiveWorkbook
On Error Resume Next
If IsWorkbookOpened("Projekt.xls", "C:Documents and SettingsfrederikSkrivebordRedd Barna") Then
Workbooks("Projekt.xls").Activate 'In case open, just activate "Projekt"
Else
Workbooks.Open Filename:="C:Documents and SettingsfrederikSkrivebordRedd Barnaprojekt.xls"
End If
Set wb = Workbooks("Projekt.xls")
wb.Activate
If Not SheetExists(wba.ActiveSheet. Range("C1").Value) Then
MsgBox "overall doesn't exist!"
Else........................................
