From what you describe, your fields should be coded as:
Code:
{IF{MERGEFIELD Cover_Type}= "E1" {IF{MERGEFIELD Overseas}<> "" "Sentence for this cover"}}
and:
Code:
{IF{MERGEFIELD Waits_Apply}= "Y" {IF{MERGEFIELD Previous_Extras}= "Y" "Sentence for upgrading waits" "Sentence for previous extras"} "Sentence for waits apply"}
If your 'Previous Extras' data field can have content other than Y or N, use:
Code:
{IF{MERGEFIELD Waits_Apply}= "Y" {IF{MERGEFIELD Previous_Extras}= "Y" "Sentence for upgrading waits" {IF{MERGEFIELD Previous_Extras}= "N" "Sentence for previous extras" "Sentence for not Y/N"}} "Sentence for waits apply"}
You can omit the "Sentence for not Y/N" if there's not output for that condition.
Note: The field brace pairs (i.e. '{ }') for the above examples are all created in the document itself, via Ctrl-F9 (Cmd-F9 on a Mac or, if you’re using a laptop, you might need to use Ctrl-Fn-F9); you can't simply type them or copy & paste them from this message. Nor is it practical to add them via any of the standard Word dialogues. The spaces represented in the field constructions are all required.
