Messages are quoted exactly as they appear on screen, so you can search this page for the text you see. It ends with answers to common questions. For how the wizard works, see the [installation wizard overview](https://help.quickbase.com/quickbase-extensions/docs/en/juiced-add-on-installation-wizard-overview). ## How messages appear - **On a step.** If something on a step needs fixing, the wizard stays on that step and shows a message in a red banner. Fix what it says and select **Next** (or **Finish**) again. Your app isn't changed until you select **Finish** on the last step. - **On the error page.** If the wizard can't continue at all, it replaces the step with an error page that reads *Sorry! It looks like we've ran into an error!*, sometimes a line that describes the problem, and *Error Code:* followed by a code. See [Error page codes](/quickbase-extensions/docs/installation-wizard-messages#error-codes). ## Error page codes | **Code** | **Message** | **Cause** | **What to do** | | --- | --- | --- | --- | | 900.0 | No extra message. | Your session expired after 20 minutes without activity.
