Dropdown list issue...
I have a dropdown list (Activity Level) in a Tab Control (Body Stats). I only want you to be able to choose the data in that if other fields in that Tab Control is not empty.
Right now I have a portal that I can choose records from MeasurementsData and it will populate fields in Tab Control (Body Stats) MeasurementsData2. Right now when people choose the options in dropdown list (Activity Level) it will give wrong calculations if the user does not have data in Weight field. Can I have something pop up to where it lets them know they have to choose a record in Portal?
