                    parserTripTake(hotelURL, hotelID, websiteID)
                    nextPageLink = ""
                ElseIf websiteID = 18 Then ........

After every function i want a literal or any other way to tell the function is finished... example after the first function finish , the literal should shows example finished now starting function 2 ...

Any help/tips/code?

Thank you

you can simplay response.write the javascript code or you can use registerclicentscriptBlock in asp.net

//vb version

Dim scriptText As String
    scriptText = "return confirm('Do you want to submit the page?')"
    ClientScript.RegisterOnSubmitStatement(Me.GetType(), _
        "ConfirmSubmit", scriptText)

hope it helps.
