	$source_field_id = 5;

	return $_POST[ 'input_' . $source_field_id ];
} );

Set a variable min/max range based on a field value.

Take a base value and calculate a range based on that value. For example, if the base value is 100 and your range is 50, the user could enter a price between $50 and $150.

This example also uses the gppr_price_range_max to handle setting the maximum price range.
