I am trying to create a custom validator for eform field. This validator needs to work based on the value from previous field(example, phone number and confirm phone number filed). I am referring:

> **[Custom Validation Rules - Bloomreach Experience Manager - The Fast and...](https://xmdocumentation.bloomreach.com/12/library/enterprise/enterprise-features/enterprise-forms/custom-validation-rules.html)**
>
> The fast and flexible on-premise or PaaS headless CMS

In code, how do I refer another field from same form and same group to achieve this?
