Hi Anders, you can try this in a calculation field in the other app:
var mon = @Sum of Monday; // from app WeekSchedule var tue = @Sum of Tuesday; var wed = @sum of Wednesday and so on var selDate =moment(@selection date field).isoWeekday(); selDate == 1 ? mon : selDate == 2 ? tue : selDate == 3 ? wed (.... and so on) : ""
var selDate gets the number of the weekday (1 = Mon, 7 = Sun). The last line read as: If selected date is Monday (= weekday numner 1) THAN (=?) take value from Monday-field ELSE IF (= : ) ... and so on ... last : "" (= ELSE show nothing (in case when no date is selected))
