Getting totals in a CFC

Question

I am trying to use two SQL calls and set a couple variables
to gather the
balance of projects left for a member.
I first find out how many projects they have total for their
account.
(available)
Then I use the recordcount to find out how many projects they
current have
active. (used)
Then I subtract the active projects from the total and get
the
'projectsleft'
What did I do wrong in this component and how can I output
the final number
(projectsleft)
I want to create a component on another page and use the
'projectsleft'.
<cfcomponent>
<cffunction name="Balance" access="remote"
returntype="numeric">
<cfquery name="UsedProjects"
datasource="#Request.MainDSN#">
Select title
FROM projects
Where dirname = '#SESSION.MM_username#'
</cfquery>
<cfset used = #UsedProjects.RecordSet#>
<cfquery name="AvailProjects"
datasource="#Request.MainDSN#">
Select projects
FROM Members
Where username = '#SESSION.MM_username#'
</cfquery>
<cfset available = #AvailProjects.project#>
<cfset projectsleft = available - used>
<cfreturn projectsleft>
</cffunction>
</cfcomponent>
Thanks!

I appreciate your submission to my question, but I am asking
cause I don't
know. I apologize for my lack of knowledge. If I knew how to
do it
efficiently I would not be asking.
Also, I know the item is wrong. That is why I am asking how
make it right.
