How can I vlookup across rows with title rows as criteria in Excel/VBA?

Question

Example

Data:

Output:

Hello, please see attached sheet. I have sheets with financial data organized by an ID column and by date rows in titles.

On sheet 1, I want to specify a date range in sheet 1 cells B1 & D1 for which profit margin would be calculated. For example, given the images below, I need a formula in B3 of output that can sum the profit values from 2/1 to 2/6 (34).

Could anyone point me in the right direction as far as VBA or even some in sheet excel formulas? Appreciate any feedback

You can use MATCH to find the ID and Dates, and a series in INDEX 's to return the required range toa SUM

=SUM( INDEX( Profit, IDRow, FromDateColumn) : INDEX( Profit, IDRow, ToDateColumn))

where FromDateColumn , ToDateColumn and IDRow are found with MATCH

=SUM(
 INDEX(Profit!$1:$1048576, MATCH($A$3,Profit!$A:$A,0), MATCH($B$1,Profit!$1:$1,0)) :
 INDEX(Profit!$1:$1048576, MATCH($A$3,Profit!$A:$A,0), MATCH($D$1,Profit!$1:$1,0)) )
