well it seems you already have it set as a "manual" running total unless you are resetting TotalMinutes on another detail section (or a header/footer) somewhere else.
to get it to appear as an option to be used in crystal's standard runnnig total change it to
if {tblTime.hours}=0 and {tblTime.minutes}>0 then 60 else
ceiling(({tblTime.hours}*60) + {tblTime.minutes},30)
