calling ASP.net  function from javascript

I'm getting the time limit from the database and then start counting down the clock.

This is my code under script tag inside aspx file

var CDTimer1 = new CountDownTimer(<%# getTimeLimit() %>);

As you can see i have put the function getTimeLimit() that returns an integer , e.g 35.

Here is the function in aspx.vb file
Function getTimelimit() As Integer
        Dim drtimeLimit As SqlDataReader
        Dim gValue As clsGetValues

' this here would get the value from the database and keep in the datareader object
        drtimeLimit = gValue.SP_DataReader("sp_TimeLimit", "@ActivityID", "25")
        If drtimeLimit.Read() Then
            Dim temp As String = drtimeLimit("TimeLimit")
            Dim value As Integer
            value = CInt(temp)
            getTimelimit = value
            drtimeLimit = Nothing
            getTimelimit = 0
        End If
    End Function

It compiled successfully but doesn't do the needed work. Somehow CDTimer1 variable is set to 0. I don't understand why. I also want to know what is the different between <%# and <%= tag and when to use them

<%= is the same like response.write

try to set your timelimit to 10 in your


if the CDTimer1 then is set to 10 then the problem is that
drtimeLimit.Read() = false

i don´t know much about asp.net only asp but have a closer look at the read function, perhaps read needs a parameter.
