Text boxes with an if, driving me crazy

[Hizaed]

Ok, I have a form is a a user name text box and password text box. Here is the code that I am trying.

public xlogin as varient
public xpassword as varient

If login.value = null then
msgbox " Enter a user name"
end if

If password.value = null then
msgbox "Enter a password"
end if

if login.value and password.value = not null then
xlogin = login
xpassword = password

docmd.close acform, "frm_login"
end if

Ok, so none of it works heh, I get a data type mismatch on the 3rd if and if I remove the 3rd if I dont get any msgboxes if I leave the User and Passworld blank. If I change the .value to .text I get an error message that I can't reference a property or method for a control unless that control has the focus. I tried a could other things but they were just shots in the dark. Thank you for any help that you can offer!
