How do I turn two values into xy coordinates?

    May 06 2012 | 1:23 pm
    I have some basic colour tracking going on, I have a linear scale of 1 to 10 for the x axis and the same for the y.
    I'm trying to create an imaginary 'grid' within the Jitter window so when ever the colour tracked is in a specific grid it can trigger something. but each grid needs to have it's own unique value so I can use the select object.
    Is there a way I can turn these into coordinates or a way I can give each "grid" it's own specific value?
