Hello!

I have a custom code handler for submitting a form. Could you help with a state variables that I should set to show form error / success manually?  
And is the state global or is it component based? Because, once I set the state inside the form, child components doesn’t seem to have it.

Thank you a lot!

Hi @khomenok,

Builder state is a global variable within the content entry. One way to use builder [custom code](https://www.builder.io/c/docs/guides/custom-code) is well explained here [Builder form questions](https://forum.builder.io/t/builder-form-questions/2094)

Furthermore, I recommend you check out our forum post [Accessing builderState in custom components withChildren](https://forum.builder.io/t/accessing-builderstate-in-custom-components-withchildren/1884) and [How to access data from Builder in a React Custom Component](https://forum.builder.io/t/how-to-access-data-from-builder-in-a-react-custom-component/2618)

Hope this helps, let me know if you’ve further questions!
