Calculate days from a date field until now

[VictorSalazar]

I am collecting a date of when someone moved in.  I then want a new field to automatically calculate the amount of days from that date.  

Does the calculation field need to be a 'calculation' type, or integer?  Also, what would the calculation look like to count the amount of days until now()?  

Thank you!

int((decimal-date-time(today()) - decimal-date-time(${locationlength})))

Got it... thanks.
