# Set or Update an Application Field Value

Rules can be leveraged to update a application-scoped field value. If a field should be set or updated based on a Form submission, the rule should be built within the Form itself instead of within the Rules Editor.

1. Click **Database** in the top navigation bar and select **Rules Editor**.
2. Click **New Rule**.
3. Enter the following configurations in the popup window:
  - **Name** - Set (Field Name)
  - **Type** - Configurable Joins
  - **Category**- Records
  - **Base**- Application
  - **Rule Type**- Field
  - **Rule Trigger** - Review [Trigger Selection](/v1/docs/trigger-selection) documentation
4. Click **Save**.

#### Configure the appropriate filters:

- Select any filter to determine the population that should be assigned a particular application-scoped field value.

#### Configure the appropriate action:

- **Field** - Select the field to update when the filtering criteria above is met.
- **Action** - Select the action for the rule to take on the field selected above
  - **Add to Values** - Adds a specific value to a multi-value or free text field.
  - **Replace Values** - Replaces the existing value with a specific value.
  - **Delete Values** - Removes all values.
  - **Add to Values from Custom Field** - Copies the data stored in a different field and appends the value. Works for multi-value prompt fields (where both the Source and Destination fields share the same prompt list) and free text fields.
  - **Replace Values from Custom Field** - Copies the data stored in a different field and replaces the value. Works for prompt fields (where both the Source and Destination fields share the same prompt list) and free text fields.
  - **Replace Values from Formula** - Allows for use of [Rule Formulas](/v1/docs/rule-formulas) to replace the value.
- **Value/Copy Value(s) from Field** - Select/enter the appropriate value/field.
