Value Of Checked Box!?

I've got the following problem:

I'm retrieving data from an SQL Server database. And I want my form to
display a checked box in the state corresponding to the value saved in
the DB. But somehow that doesn't work!?

SQL tells me the value is 1.
My ASP page tells me it's 'True'??

So I tried it like this:
<input name="checkbox" type="checkbox" value="checkbox" <%If
rsDemande.Fields.Item("lien").Value = 1 Then Response.Write("
checked='checked'") : Response.Write("")%>>

and like this:

<input name="checkbox" type="checkbox" value="checkbox" <%If
cstr(rsDemande.Fields.Item("lien").Value) = "True" Then Response.Write("
checked='checked'") : Response.Write("")%>>

But neither works. The checkbox remains unchecked!?

What am I doing wrong?
