Pulling a Record set and then using a field within that record to pull additional information from the table.

Question

I am pulling information based on the following "If" statement;
If({JCT_CURRENT__TRANSACTION.Category} = "L"
    and "cost" in {JCT_CURRENT__TRANSACTION.Transaction_Type}
    and {JCT_CURRENT__TRANSACTION.Transaction_Date} > {@Prev Week}
    and {JCT_CURRENT__TRANSACTION.Transaction_Date} <= {@Week 1})
then
{JCT_CURRENT__TRANSACTION.Units}
This works fine and I can print it on the report with other associated fields.  One of those fields is a "Cost Code" field associated with the above conditions and date set (I am pulling for one pay period week).  Of these transactions, each week different "cost codes" could be available.
One item I need to figure out another formula is associated with the cost codes that are pulled, but, I need to compare them to a different date range.
Here is how I get the cost codes that were used in a specific time frame;
If({JCT_CURRENT__TRANSACTION.Category} = "L"
    and "cost" in {JCT_CURRENT__TRANSACTION.Transaction_Type}
    and {JCT_CURRENT__TRANSACTION.Transaction_Date} > {@Prev Week}
    and {JCT_CURRENT__TRANSACTION.Transaction_Date} <= {@Week 1})
then
left({JCM_MASTER__COST_CODE.Cost_Code},6) & "001"
This gives me the cost codes used in that period but changes the last three digits to be "001" (xx-xx-001).
Now, I need to take that cost code, the xx-xx-001 and compare it to a completely different date range to get an "estimate" number.
My problem is that, because I need to use a date range in the original conditions, even after I truncate the cost code, for some reason, it stays associated with that date range.
How can I use a field from a group of records based on date, but, associate it with a competely different date range.
I hope this is clear, I am having a real hard time with this, I am fairly new, but have pretty normal working knowledge of basic formulas, etc...
Thanks, Mike
