New to AB, trying to learn Composites.
This code attempts to write an array to a composite, read it back from
the composite, and then display the results from the composite.
I'm sure the answer to this is painfully obvious to community members
with experience: why am I seeing only zeros from the second loop,
even though lastvalue at the end of the trace is accurate?
Best, :)

code:
/////////////////////////////////////////////////////////////
fi = "%1.0f";

testcum = Cum( test );
_TRACE( "initial lastval of testcum = " + StrFormat( fi, LastValue(
testcum ) ) );
for ( i= 1; i <= 5; i++ )
{
test[i] = i;
_TRACE( "test = " + StrFormat( fi, test[i] ) );
testcum = Cum( test );
_TRACE( "tescum = " + StrFormat( fi, testcum[i] ) );

farray = IIf( True, 0, 0 );
