Steve,

Can you output this as a character field? If so you can use ttoc():

set hours to 24
t1 = datetime()
t2 = t1 + int( rand() * 3600 )
lnElapsed = t2 - t1
lcMMSS = right( ttoc( {^2002-01-01 00:00:00} + lnElapsed ), 5 )
? lcmmss, lnElapsed

>Here's a formula I use to calculate seconds between two times. I want to show the seconds as minutes:seconds instead of seconds both in the text below the chart and in the label of the chart too. I was thinking I might try using the Time(0,0,0) formula to get hh:mm:ss, but I did not get the result I wanted. I could write my own formula that converts it into minutes and seconds using divide by 60, but I figured Crystal would have a built-in function I could use instead, but I still have my doubts about minutes and seconds appearing on the bar chart label and axis labels. Here's my formula. Thanks very much.
