Need a count of items which have specific values in three columns

Question

I have a spreadsheet where I need to get a count of how many records have a specific three values in three different columns. This is what I have so far, but it returns 0 results, which isn't correct.

=SUM(($K:$K="Computers")*($Q:$Q=1)*($J:$J="Microsoft Windows XP Professional SP3"))

I need to know how many records are a computer, with the value 1, running XP.

I am aware I haven't explained this well so please ask for clarification if needed. Thank you!
