# Warnings and messages

These are the messages the PDA can show and what to do in each case.

## When logging in

**Start the server first**: PizzaGest is not running on the restaurant's computer. Start it and tap **Try again**.

**Error accessing the database**: the PDA cannot connect to PizzaGest. Check that the restaurant's computer is on and that the device is connected to the restaurant's Wi-Fi.

**The database version is too old**: PizzaGest has to be updated to use this version of the PDA.

**The employee does not exist** and **The employee has not clocked in**: see [Logging in](https://docs.pizzagest.com/books/pizzagest-pda-icL/page/logging-in).

## When opening a table

<p style="text-align: center;"><img src="https://pav-bookstack-docs-uploads.s3.eu-west-par.io.cloud.ovh.net/uploads/images/gallery/2026-11/LhDseFHof0iwnjEf-pda-en-25-mesa-bloqueada.jpg" alt="Warning that the table is locked by another device" width="300" style="vertical-align: top;"></p>

**Table locked by another device**: another waiter has that order open on their device. You can look at the order, but the right thing to do is tap **Exit without changes** and wait for your coworker to tap **Finish order**.

If the table stays locked and nobody is using it, someone left it without tapping **Finish order**. That waiter just needs to go back into the table on their device and tap **Finish order**.

**The table is already closed**: the table was paid or closed from PizzaGest while you had it on screen. Tap **Choose another table**.

## When taking the order

**Still to choose**: the product has a group of [ingredients](https://docs.pizzagest.com/books/pizzagest-pda-icL/page/changing-the-ingredients) where picking one option is required, such as the dough.

**Ingredients max.**: the product already has the maximum number of ingredients its category allows.

## When sending the order or asking for the bill

**Send the order?**: some products that were already in the kitchen are [marked for removal](https://docs.pizzagest.com/books/pizzagest-pda-icL/page/changing-an-order-already-sent). Check the list and confirm.

**The order cannot be sent**: every product is marked for removal. The whole order has to be canceled from PizzaGest.

**PizzaGest did not answer** and **The bill could not be calculated**: see [Asking for the bill](https://docs.pizzagest.com/books/pizzagest-pda-icL/page/asking-for-the-bill).
