A computer program (124) that causes a processor (114) to display on a monitor (102) a value (104) of different variables (126, 128, 130, 136, 138) having a defined relationship. The program (124) causes the processor (114) to receive user input changing the value (104) of any of the plurality of variables (126, 128, 130, 136, 138) and determine values (104) for the plurality of variables (126, 128, 130, 136, 138) to maintain the relationship. The program (124) then causes the processor (114) to display the determined values (104) for each variable (126, 128, 130, 136, 138).
