Weather XML Variables

[fungun]

Are the variables that the plugin creates, like the weather alert ones, suppose to clear out after the alert has expired?
Because they are not.
I am using them now, since I can not get the "Last Alert Device" to work. It really messes with my HSTouch because the regular alert devices disappear after the alert expires, there fore I can't set things to use values to change buttons or screens.
Jon00 helped me with this script -

Sub Main(ByVal Params As Object)

        Dim AlrtTitle As String
        hs.CreateVar("wxmlAlertTitle_1")
        AlrtTitle = hs.GetVar("wxmlAlertTitle_1")
        If AlrtTitle = "" Then
            hs.SetDeviceString(1381, "No active alerts", True)
        Else
            hs.SetDeviceString(1381, AlrtTitle, True)
        End If
    End Sub

but my device still shows a warning from 2 days ago. So the variable must not be getting cleared after the alert expires.

Thanks,
Tim
