Thanks Paul. Would you be able to explicate how quotes are paired in a code example from the Mailmerge Tutorial for us ?

In the first example, "Merge Records by Category",

{QUOTE{IF {MERGESEQ} =1 {SET KEY ""}}"{IF{MERGEFIELD City}<> {REF Key}
"IF...

is the quote (in red) the beginning of a new expression? And does that expression end with the next quote before IF - or is it paired with another quote further down?

Also, the use of QUOTE..I think it's used here to return values after expressions are evaluated. Is that correct?

Thanks!
