Show the code where you get the error
Also, why are you defining PullAhead as a nullable boolean and then put an
integer in it?

Hello Herfired,
I tried with this as
Dim PullAhead As Nullable(Of Boolean)
PullAhead = Nothing
If _lblpullahead.Visible = True Then
PullAhead = Convert.ToInt32(_drplPullAhead.SelectedValue.Trim)
End If
but when I send this as a parameter to a method in
my Business Layer
its throwing this error

Am I missing some thing here?
the code is exactly the same as we discussed in our previous postings.
Thanks
