Count Records with Multiple Criteria from different sheet 
I've seen some similar questions asked but still can't figure out what formula to utilize.

Very similar is http://productforums.google.com/forum/#!topic/docs/VUN-veVHRnQ

From Sheet 2 in a spreadsheet I'm trying to count the number of records in Sheet 1 that match two criteria:

1 - If value string in column E="NNN" (this is my first filter to find the subset of data I'm interested in - values are alpha strings)

2 - If $$ value in column S="$$" (once I have the subset from above, I want to know how many meet this 2nd criteria which is a number value)

A Simple Countif (examples below) will return me the number of records that match one of those criteria, but how do I construct a formula  that will return me a count of records that match both criteria?:

=COUNTIF(Sheet1!E2:E750;"NNN")

=COUNTIF(Sheet1!S2:S750;3600)
