[Help] How to get relative prop delay Delay value (delta :tolerance) of match group by skill

Hi guys,

I have trouble when building a skill export match group to a report file *.txt form design. But I can not get the relative prop delay Delay value (delta: tolerance) of the match group.

Below is my code, please help me point out an incorrect one or any way i can get delta : tolerance value by skill

foreach( mgrpEle Mgrp_list_item_sel
     foreach( i car(axlSelectByName("MATCH_GROUP" mgrpEle))->groupMembers
          if(i->net->name != nil then
               netname = i->net->name
          else
              netname = i->parent->name
          )
         comp1 = car(parseString(car(parseString(i->name ":")) "."))
         comp2 = car(parseString(cadr(parseString(i->name ":")) "."))

         del = i->net->rpd
         fprintf(myReportNet "%s %s %s %s %L\n" mgrpEle netname comp1 comp2 del)
     )
)

Thanks,

Jared.
