Autosum totals for amounts in multiple instances of table?

i'm using livecycle es2 create expense claim form. have no trouble calculating sum of values in column in table repeatable rows. however, form more complex. you'll see, each item (expense) table. clicking button adds new instance of table. no problem calculation gst, either.

 

where gets tricky trying dynamically calculate grand totals expenses incurred , gst. in different table, can see here.

and here's grab of object hierarchy illustrates how built this.

is complex, or there way dynamically calculate grand totals, regardless of how many instances of expensedetails there may be?

nothing complex calculate, using formcalc should big time!

 

using formcal every instance should :

 

sum($.resolvenode("expensedetails").row1[*].gst)

 

row1[*] specify every instance of object
