Why SUM is not working in SSRS

Question

Hi,
I'm new to SSRS and am having a problem. I am trying to replicate the value of sum(sum(field)) using lookupsets and custom code function.  I have this little function which works fine.
PUBLIC SHARED FUNCTION CalcPTD2(LookupArray AS OBJECT) AS INTEGER
     DIM i,Total AS INTEGER
     Total = 0
     FOR i = 0 to UBOUND(LookupArray)
           Total = Total + CINT(LookupArray(i))
     NEXT i
 RETURN  Total
END FUNCTION
I call this function with the following call:
Code.CalcPTD2(Lookupset(FORMAT(Fields!REALDATE.Value,"Long Date"),FORMAT(Fields!CallbackDate.Value,"Long Date"),Fields!DailyHours.Value,"DataSet4"))
The output of this function is a row of data consisting of 28, 47, 35, 43, 41
If I use COUNT on the output of the function like this COUNT(Code.CalcPTD2(Lookupset(FORMAT(Fields!REALDATE.Value,"Long Date"),FORMAT(Fields!CallbackDate.Value,"Long Date"),Fields!DailyHours.Value,"DataSet4"))) I get the
result of 9
If I use SUM on the output of the function like this SUM(Code.CalcPTD2(Lookupset(FORMAT(Fields!REALDATE.Value,"Long Date"),FORMAT(Fields!CallbackDate.Value,"Long Date"),Fields!DailyHours.Value,"DataSet4"))) I get the result
of 353
I set up a global counter and it showed it was only entering the function 5 times as expected. So where is the extra data coming from? Is this an invalid use of SUM or COUNT? What is a replacement? Earlier in my report I reference SUM(SUM(Fields!DailyHours.Value)
which is the result I am looking for. I can't reference it here because the matrix is associated with another dataset. And splitting it out into another matrix is not an option.
Thanks in Advance
Ann

Here is a copy of my expressions and a copy of my data. The expressions match up going from left to right
Code.CalcPTD2(Lookupset(FORMAT(Fields!REALDATE.Value,"Long Date"),FORMAT(Fields!CallbackDate.Value,"Long Date"),Fields!DailyHours.Value,"DataSet4"))
sum(Code.CalcPTD2(Lookupset(FORMAT(Fields!REALDATE.Value,"Long Date"),FORMAT(Fields!CallbackDate.Value,"Long Date"),Fields!DailyHours.Value,"DataSet4")))
count(Code.CalcPTD2(Lookupset(FORMAT(Fields!REALDATE.Value,"Long Date"),FORMAT(Fields!CallbackDate.Value,"Long Date"),Fields!DailyHours.Value,"DataSet4")))
PUBLIC SHARED FUNCTION CalcPTD2(LookupArray AS OBJECT) AS INTEGER
     DIM i,Total AS INTEGER
     Total = 0
     FOR i = 0 to UBOUND(LookupArray)
           Total = Total + CINT(LookupArray(i))
     NEXT i
 NumberTimes  =   NumberTimes +1
RETURN  Total
END FUNCTION
