The form post will send the checkbox value as character. I just use a condition to set the value passed.

'Client form with checkbox being posted
<INPUT TYPE=CHECKBOX NAME=CB1 VALUE="Y">

'On server ASP being posted to:
CB1=Request.Form("CB1")
If CB1="Y" then
   CB1=true
else
   CB1=false
end if
'Now simply update your logical field in the recordset with CB1
