Divide by zero issue

My report needs a calculated field called Daily Hours. To get this I would do the following in a perfect world.

({pusess.sesshours_no} / {pusess.scheddays_no})

But because the field {pusess.scheddays_no}) has NULL values it falls over saying in can’t divide by zero.

Now I tried     if isnull ({pusess.scheddays_no})  then 0.00 else ({pusess.sesshours_no} / {pusess.scheddays_no})

But Crystal gets in a loop of some sort and crashes. The only way I can make it work is to change all the NULL values to zero and use the following: -

if {pusess.scheddays_no} = 0 then 0.00 else ({pusess.sesshours_no} / {pusess.scheddays_no})

If anyone else has a better idea please let me know
