Pulling Results Between Dates

I've linked access to an external database and created a query to pull results from the linked access table that was between certain times on certain dates (i.e. between 11/12/2007 11:01 AM to 12/13/2007 12:01 PM). The query I have thus far is "SELECT * FROM TABLE1 WHERE DATETIME >= #11/12/2007 11:01 AM# AND DATETIME <=#12/13/2007 12:01 PM#". That works, but I want the date and time to be changeable through text fields on a form. Something like "SELECT * FROM TABLE1 WHERE DATETIME >= #forms.form1.startdate forms.form1.starttime# AND DATETIME <= #forms.form1.stopdate forms.form1.stoptime#". The dates are going to be automatically generated according to other parameters but the times are going to be entered manually. How can I accomplish this?
