I got a request to publish my "sollution" to this list.

The thing was that the function didn't end up doing anything (it wasn't a 
closed circuit) so the values didn't get forwarded to the patches where I 
thought my data was missing from.

Solution: I put a "Image to String" and a "Billboard" as the last patch, while 
I completed the function.

While I'm at it, I can really recommend (sort of) collision testing with the 
patch "Image Pixel", just make a separate image mask for the buttons and assign 
a unique color value to each button. Compare the current color with "String 
Compare". Saved me from a lot of complicated math. The best part is the buttons 
doesn't need to be rectangular, they can be any shape you wish.
