i know you can easily condition the format of a field based on its values but what i'd like to do seems to extend outside the power of the condional format menu item. basically, i'd like to display in red the values of a laboratory test on a form when they fall outside the normal ranges for a) males and when they fall outside the normal ranges for b) females. now since you're either a male or a female, and the patient's gender is entered ('M' or 'F') on a different form the questions becomes how do you ask Access to read the gender and tell the lab test field display itself the color red when the value therein is not 14 to 18 for males or to go to red when the value therein is not 12 to 16 for females?
