CRUD - Action column not working

[donjohnson24]

Yet another query, I afraid
I've eventually got CRUD to work on https://donjohnson24.co.uk/availdogs.php
and it does the job of controlling the display at the bottom of https://www.donjohnson24.co.uk/homeonth ... ing.me.uk/
but although records can be added, and existing records appear, the Action column is not active to allow editing, etc
I can't see any reference to the Action column in the Help file, and only the Language tab enabling amending the title trxt
Please suggest what I have I missed

Maybe you have made the text labels empty?

These are related but should be fixed:
- the document type of the page is wrong. It should be set to html5
- the jQuery version is outdated, It should be jQuery 3.x

The empty Action column was due to the fact that the Column 0 Listview setting was set to No and it needs to be Yes

Although an entry is not strictly needed in Column 0, it could be handy for quick identification for the person modifying the Availability calendar file.

Thanks for the heads up on the parameters - that's what comes from copying old pages instead of starting from scratch.
