MATH multiply addition function, % percentage discount
Tried to get a value -7 with a MATH function, but does not work, always get -5-2 (which is -7, but somehow tosca does not show -7), message appears translation is succesfull however test blocks;
Tried above function, also tried to switch Datatype to Numeric i.s.o. String. Sub-total is a buffer.
Can someone see what I need to adapt to get the value valid ?
