my columns do not calculate with dates

[#1]

I am trying to get a running total between dates and the date below function does not work - suggestions? Please see attached picture

[#2]

Thanks for all your help!!  It finally fixed when I actually put the medical record # in the table and removed the patient ID and the calcs appeared when I changed to if(below(total MR#)=MR#,(Admitted-below(total Discharged)))

Again thank you.
