Suppress a field

Can this be done? I have 2 fields that are not empty. Field 1 is called COMPANY and field 2 is called Full Name. I want to suppress the 2nd field (Full Name) when it has the same name as field 1 (COMPANY), example of what I have now: Bob's Flooring (COMPANY) Bob's Flooring (Full Name) but if the field 2 has a different name (David Smith) than field 1 (COMPANY) then I want field 2 too show also. This is being used in an address block on a letter.

var r = TaggedDataField("COMPANY");
if (Field("COMPANY") != Field("Full Name"))
   r += "<br>" + TaggedDataField("Full Name");
return r;
