comment help please pip counter multiple pair

[Richard]

I have a managed to set up a comment to show on the screen showing the pips for the open positions on each pair,
but i am trying to show the combined amount for multiple pairs

eg e/u 20pip
g/j 40pips
u/c 50pips

combined total 110 pips

( Price() - OrderOpenPrice() ) / MarketInfo( OrderSymbol(), MODE_POINT );

how can i change this to show the combined total


Cheers
