initialze the variables with -1 and then assert
add the following to the rules as the first eval condition
rule "gst_rate_ol"
eval(QuoteUpdater . getQuoteLevelGSTRate () == -1 )
rule "NZ_SD"
eval(
QuoteUpdater . getQuoteLevelGSTStreamRate ( ) == -1) ;
QuoteUpdater . getQuoteLevelStampDutyRate ( ) == -1);
QuoteUpdater . getQuoteLevelStampDutyAmount()==-1);
)
rule "gst_stream_rate_ol"
eval(QuoteUpdater . getQuoteLevelGSTStreamRate () == -1);
Tell me if it works
