I want to create a formula that will suppress 2 fields if another field does not = a certain value. 

 

The fields I want to supress are:  'Internal Record Number' and 'Box Number' & whether these fields are suppressed or displayed will depend upon a value in the field called 'Record Type'

 

I tried to create a formula using the Box Number field to begin with:

 

If ({RecordType}='Blue Collection'
or {RecordType}='Yellow Collection'
or {RecordType}='Mixed Media Collection')
     then {BoxNumber}
          else ""

 

I was hoping to supress the field 'Box Number' in the records where 'Record Type' doesn't = Blue Collection, Yellow Collection, or Mixed Media Collection.  However, I can see that it doesn't supress the field, it just makes the value for 'Box Number' blank.

 

What formula would I use if I wanted the 'Internal Record Number' and 'Box Number' values to be displayed only in those records where 'Record Type' = Blue Collection, Yellow Collection, or Mixed Media Collection?
