Hi all,
 
Am a real novice at Crystal, and am having difficulty with something which I'm guessing should be quite easy!
 
Need to find the highest value from a table and also the lowest value.
 
Quite happily I can use the formula of 'Maximum' for the highest number and 'Minimum' for the lowest number.  Unfortunately though in my numbers I have a number of zeros which I do not wish to include?  How could I write a formula to find my lowest number, discounting all zeros?
 
Thanks loads for any help!

you can either exclude the rows altogther using the select expert...
table.field>0
 
or you can use a running total to exclude the fields from the evaluation...
name=min
field to summarize=your field here
type=minimum
evalaute=use a formula
table.field<>0
reset=never (assuming you are not doing any group level evaluation)
place in report footer (RTs do not work in headers)
