SQL2 = SQL2 & " FROM Exit_TipoCamionFlete"
SQL2 = SQL2 & " order by DescripcionCamion"
'response.write" " &sql2
'response.write scamion
'response.end
rs2.open SQL2 ,cx2
Response.Write "<select name=""scamion"" onchange=""javascript:id_TipCamion();"" >"
Response.Write "<option value=0>Seleccionar</option>"

Do While Not rs2.EOF
