Yep...sure do...and that's all fine and dandy...

2- in my previous project (called int.pcb, wonder why...), i didn't read porta before enabling interrupts (to clear potential mismatch), BUT ra3 was not enabled for int in IOCA register so it didn't trigger interrupt if not tied to vdd with a wpu.
But!....3 posts ago...one of those sentences is STILL not like the others...
And I had a look at your code...one small thing (I think) and you'll be set...
