| What you see | What it means |
|---|---|
| You keep landing on the sign-in page | You are signed out, or you were signed out by time. The request pages are closed to anyone who is not signed in. Sign in and click the menu entry again. |
| “Session expired” | The page had been open a long time. Reload it and submit the form again — what you typed is not sent until you press Submit, so retype and resend. |
| “The sheet is not locked for editing” | You never took the lock, or it was broken by the developer. Press Lock to edit, then save again. |
| “Locked by …” | Somebody else holds that centre's sheet, and it stays theirs until they press Unlock. Ask them — or, if they have gone, ask the developer to break the lock. |
| Save is greyed out | Either there is nothing to save, or you do not hold the lock. Both are normal. |
| Your request is not in the list | You are probably on the other kind. Change duty and intrastation keep separate lists — check the menu group you came from. |
| The station you want is not offered | A station needs two people on it before an intrastation request can be raised against it. |
