Each contractor has its own jobs, gangs, leave and colour.
Untick "Show on week" to keep a field hidden. Hidden fields only show when you click the job card, the same way you edit it.
Edit users can change the planner. View only users log in with their first and last name. They see their own gang's jobs, plus another gang's jobs on days they cover for it (leave cover or the weekly crew line), so the name must match exactly. Users with "Manage users" can add and remove users. Only Permit can give that right.
If the planner is published at a new address, paste it above so the copy button gives the right link, and update the SharePoint link too. A new tracker must be a Google Sheet with a tab called Planner Data, headings in row 1, and edit access for the planner owner. The planner data moves into it as soon as you save.
These settings are shared with everyone who uses the planner.
Put {permit} in the link where the permit number should go, for example https://example.com/search?q={permit}. A site without {permit} opens normally and the permit number is copied, ready to paste.
