So I changed the code to this....

ChDir "\\tangent1\PLP"
Workbooks.Open Filename:="\\tangent1\PLP\Ongoing Summary.xls",
UpdateLinks:=3
ActiveWorkbook.Save
ActiveWorkbook.Close
ActiveWorkbook.Unprotect
ActiveWorkbook.UpdateLink
ActiveWorkbook.Protect

Sitll doesn't work... I get the same error  message Run time error
1004 you cannot run thios comman on a protected sheet.

Any other ideas???
