The CodeCreator makes malformed expressions when changing the parameter and also changing the output value. In the screenshot the `.currency` part of the expression should be after the parenthesis. That is the expression should be TR.PriceClose(Sdate=0M).currency and not TR.PriceClose.currecny(Sdate=0M). This happens with any field and not just TR.PriceClose CodeCreator-Screenshot.png
