Not automatically, no.

A “Book” has nothing to do with individual files' settings … You can synchronize lots of things in a Book, though, and Master Pages is one of them. Try it — I think Baseline Grid is not a Master Page setting, but a 'global document' preference instead, but there are several different ways of defining one, so you might get lucky.

Next time, create a blank file containing just one or two pages, and all the styles and settings you can think of. Then save it as a template, and use this for all of the new documents. You still cannot change any random stuff throughout your entire book, but at least every document will start out with the same settings.

I'm not an expert in FindChangeList ops (I still use the “old style” findchangelist, albeit much enhanced over the years by yrs truly ;) ), but the syntax seems correct. Double-check if there is one single tab, and no spaces at all, between each command — I've read elsewhere that's a sure killer.

It doesn't explain why your InDesign goes out of whack, though. Malformed lines usually are plainly ignored.

Oh, by the way, to insert a in a post on this forum, you have to type two of them: \. And if you edit your post, the double 's will have disappeared and only occur once, so you have to scrutinize your post again for all and double . Woe on you if you forget one, because you have to edit again, and then you're sure to miss yet another. Endless fun.

A paragraph is anything between two returns, so check if you don't have a hard return at the end of the first line.

Are you mixing up GREP Find and Replace and GREP styles? The latter is sort of automatic 'replace' (of character styles only), and can be set in your Paragraph Style — only once, since it's “in” a style, and then your formatting Char Style will be applied automagically. It's sort of like your nested styles, but better because it allows far more exact control. And yes: you'd typically use one or the other.

(All of this is only if you have CS4 or newer, of course.)

Can you describe in more detail what you are doing? I never have to put variables on a live page, mine are always on master pages. Works a treat, too.

Perhaps they are set up to pick up a certain paragraph style, and you accidentally applied that style to blank lines, as well as the 'correct' paragraphs — that'll throw off InDesign every time.

Yup, seen it often enough.

Check if you have assigned the paragraph style for the text variables to blank lines, just before the one it ought to pick up. A single 'next page' page break also counts as a separate paragraph, and in my experience this is the culprit most of the times.

Your English is fine — I bet it's better than my Peruvian (:D)

The trick is to search for any string of digits, just as long as the very last one is odd (or even). Try this:

bd+[13579]b

The b marks a word boundary — that is, when at the left of a 'word character', there may not be another word character; it's the same when it's to the right of a 'word character'.

d+ is any digit, and the + means you can have one or lots of them.

[13579] means any single character in this set, so it will match '1' or '3' but not '2' or '?' or 'a'.

Then another b follows, to ensure this is the very last character in the search string and no other word character follows.

(A 'word character' is, according to InDesign, 0 to 9, A to Z and a to z, as well as all accented characters, and even the alphabetical characters in Greek, Cyrillic, and many more. It's by definition not anything like a space or punctuation — anything that separates words from each other.)
