[SOLVED] Finding Equivalent of Maximum Value in Another Sheet

Dear all,
Here's my issue:
I have to sets of data, each in a sheet with the first column as identical for both sheets. Sheet2 contains two series of 6 rows, each for a specific first column (""B Code").

Now I want to find the values of "TCT-C" column in sheet1 (for each range of 6 rows that the "B Code" is match) which corresponds to the row number that "TCT" in sheet2 is maximum (again for 6 rows). The point is, I need to shift to another series of 6 rows in sheet2 once the "B Code" does not match.

Thanks in advance
