I'm using a calculation condition to control a chart trend line. I want to have the user select at least one Specialty team from the multi box for the chart to show a trend. I am using the statement if(count(distinct(DaysFilled.Specialty))>0,1,0) then I display a error message to select at least one specialty team. It works when I go into it originally is set to zero, but when I use the Clear Selections button it deflauts back to DaysFilled.Specialty all selections. I want it to go back to the Error message of you have to make at least one selection.
