Suppressing Fields question???

[TSur]

I am trying to Suppress a fields based on if a different field is that same. Anyone know what I need to do for this?

this is what I am trying to do, but I am not very good with crystal reports yet...

If OrderID is the duplicated then:

suppress lastname, firstname and phonenumber.

[TSur]

the way it is now is that it just suppresses order ID number.
