Atomic Perception

Your variable naming, seems weird to me. Don't name the variables you are passing the same as the global variables you have defined outside of the function call.
For instance.
void area_check(vector position, lastpoint; int numvalue, numberhold,size, len,endp,lasttest,another,Test)

void area_check(vector passed_position, passed_lastpoint; int passed_numvalue, passed_numberhold,passed_size, passed_len, passed_endp, passed_lasttest, passed_another,Test)

Also try to avoid variable names that could be functions, such as size and len.

Sure, connect the other sop to the second input of the wrangle, and you can fetch data from that input as well.

Try placing the python node right after the Font node. not at the global /obj level.
