[amibroker] Problem calculating Sum of Equities for Watchlist

["Herman vandenBergen" <psytek@xxxxxxxx>]

<SPAN 
class=250190904-13122003>Hello,
<SPAN 
class=250190904-13122003> 
I need an 
Exploration that calculates the sum of equities for a watchlist. This has 
to be an looping solution because I want to do this on the fly while 
dynamically changing system parameters, I cannot use 
composites.  
<SPAN 
class=250190904-13122003> 
Below is 
a simplification of what I have but the sum of Equities in the last 
column keeps changing because the individual equities (based on SetForeign()) 
keep changing. I confirmed this with DebugView. Something is out of 
sync... Can somebody tell me w<SPAN 
class=250190904-13122003>here I 
went wrong?
<SPAN 
class=250190904-13122003> 
Many thanks for any 
help you can give,
