You're doing this:

if there's a 245 field:
    for each 245 field:
        print subfield $a
        for each subfield $n or $p:
            if it's $n:
                print "<br/>" followed by the subfield contents
            else if it's $p:
                print " : " followed by the subfield contents
            end
        end
    end
end

But that doesn't process 245$n before 245$p.  So use the following 
logic, or something like it: 

for each 245 field:
    print subfield $a
    for each subfield $n:
        print "<br/>" followed by the subfield contents
    end
    for each subfield $p:
        print " : " followed by the subfield contents
    end
end

(The outer conditional seems unnecessary to me, but I could be wrong).

Does that help?
