Thanks for both responses. Using various suggestions in this forum, I'm using INCLUDETEXT fields as the two alternatives for an IF field, to bring in text that is specific to just one company or the other. This is especially useful for the front matter, but it's turning out possibly too complex for Word. For some reason the first few paragraphs (actually the title, pub number, etc) aren't brought in. And when I switch from one company to the other, one little logo graphic from the first company is left anchored in the header of the cover page (which the other company might not appreciate). In other words, these packages aren't air-tight. Any further suggestions in how to make the INCLUDETEXT behave more "neatly"?
