Crystal Reports Minute conversion to hours:minutes

Message

     I am trying to convert minutes into an hour: minute format.  In MS Access I have used a Mod function that looked like this:
in a calculation field I placed the following formula:

=([My.Field]\60 & Format([My.Field] Mod 60,"\:00"))

Where My.Field would look like 1440 (minutes) and it would convert it to 24:00 (hours:minutes)

Is there a similar formula for Crystal XI?

Thanks,

Kevin
