Have designer's notebook I've used (template I devised) for three years. Now all of a sudden, irrespective of any particular update/change of software (or so I think), the TOC won't update. I'm specifically saying that it won't pick up my latest date (done as a "normal" style, and seemingly same as those TOC entries that DO still work).
As I said, each day is a heading done in "Normal" style, and up until May 5th, the TOC updated fine. After that, it simply isn't updating the TOC. Whether I:
1) update in the "Update Table" tool embedded in the "Contents" header, be it the page only or the whole table option...no changes, or
2) Go to the "References" tab and select "Update Table".


...it is the same result, NADA.
I at first thought maybe I'd exceeded the number of entries, so copied out and started a new file from the original template, pasting in all entries since the start of my second year here at my employer's. This made no difference (last update still May 5th entry). I've even made sure that the present file, smaller and newer than the original, is not saved in "compatibility mode."

Thanks for any recommendations.

Normal style is never something that should be picked up in a TOC!

Headings should be in a heading style, preferably one of the built-in styles (perhaps modified for your formatting requirements). That is the easiest way to get something into a TOC.

First, thank you Charles for your advice. I'll take it and apply it, since I'm at the beginning of this year's iteration of the Designer's Notebook, and fix my template file to carry the fix you recommended as well, so it works better in the future.

Second, I found that the problem was apparently that I had copied forward for the 6th of May entry and pasted a version from clip-board that did not carry the functionality that feeds the TOC. I went back, caught up this issue and fixed it forward, through the current entries from May 5th on, and VOILA'...all is well in my Word-world again.

Thanks to all who considered this issue. I'm closing out now on this one.
