Crystal Reports suppress line formula

Message

   Hi:

If I have a formula:

If ({Group5_csv.ObjRecordType}=‘Archives Collection’
or {Group5_csv.ObjRecordType}='Mixed Media Collection'
or {Group5_csv.ObjRecordType}='Oral History Collection')

     then ‘Collection Title:     ‘ &  {csv.ObjCollectionTitle}
          else “”

Instead of having the formula say 'else blank,' how can I make it say
'else suppress line'?

PS  Thanks for all the help you guys have given in the past--you are geniuses!  I greatly appreciate your help.
