User profile field used to filter view? OKay - I'm either brain fading or truly confused (probably both).

I need to filter a view based on the value of a field, but in a unique way. The content type (task) has a field (location) which is also used on the user profile. I need the view to only show those tasks which have the same value as the logged in user in that field. What the *&amp;% am I missing?
