## Why are some of my results empty?

Your zapbot collects results as soon as your user answers the first input. If other inputs have a blank answer, it means the user never answered them and left the bot.

## How can I delete a block or an edge?

You can right-click on most elements in the graph to open up a contextual menu with delete and other options.

## Is human takeover available on Zapbot?

Live chat is not natively integrated. Zapbot is specifically built for async chats. You can still have a human takeover feature using the [Chatwoot block](https://edesy.in/docs/zapbot/integrations/chatwoot). It will open a Chatwoot live chat box whenever the block is hit.

You can also implement great customer support with Zapbot by using a ticketing system such as [Freshdesk](https://freshdesk.com/) or [Zendesk](https://www.zendesk.com/). You can create a ticket each time your user answers the bot.

## How can I change my password?

Zapbot doesn't store any password. Its login works with Google, GitHub, and Magic link email authentication.

## Can I set a variable with the Script block?

No, the script block is only meant to execute a script. You can't set a variable with/in it. If you need to set a variable with some code, you can use the [Set Variable block](https://edesy.in/docs/zapbot/logic/set-variable).
