Mover ImageView Question

[samperizal]

Greetings.

in the following code
If s.Val (Main.n_latitud) = 0 AND s.Val (Main.n_longitud) = 0 Then
ver_mapa.Visible = False
else
webresultado.Height ver_mapa.Top = +20
ver_mapa.Left = (Activity.Width / 2) -30
ver_mapa.Visible = True
ver_mapa.BringToFront
ver_mapa.Invalidate

End If

I can not wait to run imageview ver_mapa but if I comment the lines of top and lef if you see that's what I do wrong?

Thanks in advance
