I have a problem i need to work out the difference between two items one was a dimension the other a measure i have changed the dimension to a measure but i understand this does not change it to a number neccesarlily i'm a little new to this its type is a character string even though i forated it as a number i remeber from a recent training course that i need to specifie to the designer that this should be a measure not a dimension is there any other way i can subtract these items without getting the designer to change the it to a measure from a dimension?????
Please help any advice would be great
