How to Declare A variable in VB?
Its new for me i cant solve an in following code.

nm = Request("full_name")
    cn = Request("contact_no")
    em = Request("e-mail")
    msg = Request("message")


    Set conn = Server.CreateObject("ADODB.Connection")
    connectionString = "DSN=MyDSN"
    conn.Open(connectionString)

    sql = "INSERT INTO contact VALUES ('"&nm&"','"&cn&"','"&em&"','"&msg&"')"

    REM Response.Write(sql)
    conn.execute(sql)
    conn.close();
    Response.Write("successfully submitted")

推荐答案

在名称前加上Dim字样:

Put the word Dim in front of the name:

Dim nm = Request("full_name")
Dim cn = Request("contact_no")
Dim em = Request("e-mail")
Dim msg = Request("message")
