How to display the result of a substraction of two box

[christshis]

Hi All,

I am trying to display the result of the difference between two boxes in a new unbound text box.
Basically, I have a box called "Initial Downtime" --> display the system downtime
Than another box called "uptime"--> display the time the system cam back up.
I would like a third to display the difference between the two time
Any ideas on how to do this in a form?

Any help will be gratelly appreciated
