displayalerts

I want to be able to update the links in a worksheet without the alert box appearing. I'm still getting a message alert asking to update links yes/no. What am I doing wrong??

Application.DisplayAlerts = False
Set xlWorkbook = xl.Workbooks.Open(OpenPath)
xlWorkbook.UpdateLink Name:=ActiveWorkbook.LinkSources
Set xlWorksheet = xlWorkbook.Sheets("Neph")
xlWorksheet.Activate

Don't you need Excel.Application.DisplayAlerts = False
