# Must be equal to another local field

This rule is a similar concept to the rule [Cannot be Equal to Another Local Field](/blocworx-documentation/bloc-editor/managing-a-field/field-rules/cannot-be-equal-another-local-field.md) only it is the opposite check.\
\
With this rule, the value of the field must be equal to another local field in your bloc.

{% hint style="success" %}
Hint: This is most commonly used in conjuction with rules like [Populate another local field with data from elsewhere](/blocworx-documentation/bloc-editor/managing-a-field/field-rules/populate-another-local-field-with-data-from-elsewhere.md). You could set a value localy and then if you would like to make sure you are using the right value then this rule could be set to a field that contains a value that has been pulled from another bloc.
