The condition that if the field contains two dashes ("--") do not print anything is working, however it leaves an empty/blank line. I'm missing some little item in the syntax.



{IF{MERGEFIELD Bus_Address_2}<> "--" "{MERGEFIELD Bus_Address_2}"}

Thank you for any suggestions. I read the very detailed document in the Sticky section, however it does not appear to cover this situation.

That's because you've left the paragraph break/line break that's creating the empty line outside the IF field. Instead of being constructed thus:
{IF{MERGEFIELD Bus_Address_2}<> "--" "{MERGEFIELD Bus_Address_2}"}¶

tt should be constructed thus:
{IF{MERGEFIELD Bus_Address_2}<> "--" "{MERGEFIELD Bus_Address_2}¶
"}
Scenarios like this are actually dealt with in the Mailmerge Tips & Tricks thread, in the note under Mailmerge Empty Line Suppression
