(cfif) check query for date, not working

Ok, I've racked my brain trying just about every combination except the right one!:) and its really starting to get to me...

Basicly what I am trying to do, I have a form where the user selects a project, which onchange submits itself, and does a query based on that selection.
the next field is a calendar, the user selects a date. now when the form is submitted, I want to check the db to see if there is already an instance of that date, if there is, only insert part of the form, if there isn't an instance in the db of that specific date, insert the whole form. the code is as follows:

<cfquery datasource="intranet" name="chk_sl">
select sl_id, date
from shiftlog sl
where date = form.date;
</cfquery>
<cfif chk_sl.date eq form.date>
<cfquery datasource="intranet">
INSERT INTO shiftlog_details
(sl_id, proj_num, supervisor, stime, etime, ts)
VALUES
('#chk_sl.sl_id#','#form.proj_num#','#form.supervisor#','0000-00-00 #form.stime#:00','0000-00-00 #form.etime#:00',#now()#)
</cfquery>

...

<cfelseif chk_sl.date neq form.date>
<cfquery datasource="intranet">
INSERT INTO shiftlog
(date, status, createdby, ts)
VALUES
(#form.date#,'In Progress','#request.factory.getUsers(filter='userID=#session.user.userID#').firstName# #request.factory.getUsers(filter='userID=#session.user.userID#').lastName#',#now()#)
</cfquery>
<cfquery datasource="intranet" name="get_last_sl">
select max(sl_id) as sl_id
from shiftlog sl;
</cfquery>
<cfquery datasource="intranet">
INSERT INTO shiftlog_details
(sl_id, proj_num, supervisor, stime, etime, ts)
VALUES
('#get_last_sl.sl_id#','#form.proj_num#','#form.supervisor#','0000-00-00 #form.stime#:00','0000-00-00 #form.etime#:00',#now()#)
</cfquery>


now with this I keep getting multiple entries of the same date, its asif the cfif isn't working for some reason, and inserts no matter what.
sorry for the messy code, I appologize if its hard to read/follow.
