Count based on letter designations and dates

[Karleajensar]

On the attached example have two worksheets within one file, MASTER and INFO.

In INFO-B3, I need to count the number of times that MASTER-column [I] shows a value under 10000, MASTER-column [H] shows dates in 2006, MASTER-column [K] shows the letter "A".

In INFO-B4, I need to count the same information with the exception of MASTER-column [I] showing values between 10000-24999. The same for B5 and B6, with B6 showing values over 50000.

THEN, I need INFO-B11 thru B14 to show the same information but only when "AJB" appears in MASTER-column [G]

Thank you very much for your help. You folks are amazing.
