stuck combining multiple INDEX match formulas

[Little_Ghost]

Hi everyone,

I've been fumbling around with multiple INDEX MATCH formula's for a couple of days now, but I seem to be unable to figure out how to combine them.
What I need them to do is check if column A = Yes and Column B = No and if those conditions are true look up the correpsonding value in column C and return that. Then do it again for the next row, and again, and again....
It should only return values when the conditions are met. The values inbetween should be skipped.
They need to be returned in a ROW.
I tried to make it a little cleared in thes google spreadsheet:
https://docs.google.com/spreadsheets/d/1kL6hic3zLQCB0pPdQ6MocVWds8UG6RHn0KWvxbPQsxA/edit?usp=sharing

There are already 2 formula's on the sheet (3 if you count the duplicate where I included a little "error" handling) so you can get a better idea of where I am at (at least with the thought proccess).

I hope someone here can help me out :S

Try this array formula:

=INDEX($C$4:$C$16,SMALL(IF($A$4:$A$16="yes",IF($B$4:$B$16="no",ROW($C$4:$C$16)-ROW($A$3))),COLUMNS($A$1:A1)))

Steve! That was amazing; both in time between Q and A and in the fact that it works!!!
Not sure about pro's and con's of array formula's but I guess I'll jus stick to this one for now and try to convert it to a non aray based formula whenever I have the time.
Time to look into the workings of the formula so I understand the internals

***EDIT***
Aaaai! found the first problem:
The result has to be displayed in merged cells (6 columns). Array formulas don't like that :S

If you unmerge the cells, type/paste the formula, ctrl+shift+enter, you vna merge the cells again and the formula is accepted but it then counts 2 columns which means it skips one entry when it finds 2 entries underneath eachother that it should display...

got the above problem solved by replacing COLUMNS($A$1:A1) with COUNTA($E$5:E5,1)
