I have created the below-listed to disable a control if the values of two global variables do not match. However, the control is not being disable if the condition "exists." Furthermore, an error occurs. Thank you

VB

Private Sub DisableControls()
        Try

            If (obj.gblDestinationCountry <> "") And (obj.gblOriginCountry) <> "" And obj.gblOriginCountry <> obj.gblDestinationCountry  Then

                'txtReference1.Enabled = False


            End If

        Catch ex As Exception
            ScriptManager.RegisterStartupScript(Page, GetType(Page), "Error", "alert('An error occurred!');", True)
        End Try

    End Sub

What is the error code and what line(s) is it pointing to? Remember, we can't see your screen.

Why don't you try nested if's?

Example:

VB

Private Sub DisableControls()
Try
  If gblDestinationCountry <> "" and gblOriginCountry <> "" then
    If gblDestinationCountry <> gblOriginCountry then
      txtReference1.Enabled=False
    End If
  End If
Catch ex As Exception
  ScriptManager.RegisterStartupScript(Page, GetType(Page), "Error", "alert('An error occurred!');", True)
End Try
End Sub

<EDIT> Can you tell me in what line do you have an error? Maybe, we can work on that. </EDIT>
