Rich Text Button Help

Hi Bethany,
App Token's are associated to an App, but not a user. The user you removed may have been using a User Token which I don't recommend for a button in case the user gets removed (as in your case).

I assume by every record on a page, you mean every record of a child table within a form. For that I'd recommend either that you just tick a checkbox (skip steps 2, 3 & 4), or have a button that ticks it for you:

1. Add a field in the parent table (I'm guessing you have an events table or similar?) called "Mark All Invited"
2. Add a formula button (I totally recommend getting the Magic Buttons app from the Quick Base App Exchange)
   "<a class='Vibrant Alert' style=\"width:310px; text-align: center;\" href='" & Dbid() & "?a=API_EditRecord&rid=" & [Record ID#] & "&apptoken=yaaaaaaaaahhhhhhoooooooo&_fid_101=1&rdr=" & URLEncode(URLRoot() & "db/" & Dbid() & "?a=dr&rid=" & [Record ID#]) & "'>Mark All Invited</a>"
3. Replace yaaaaaaaaahhhhhhoooooooo with a new App Token (App Settings > App Properties > Manage App Token)
4. Replace 101 with the field ID of your new "Mark All Invited" field you made in step 1.

So now you have a button that just ticks a box in your parent record (or just a tick box called called "Mark All Invited").
Next you just need to create a QB Action that edits the related contacts.

1. Trigger: "Mark All Invited" changes and changes to True
2. Action: Edit Contacts, copy "Mark All Invited" to "Invited"

That's it!
