Here's how to link hidden fields and update values base on dropdown select.
1. Add a text box field then hide the field and make it read only
2. Add a condition "Update a form field value"
3. In the condition window follow this settings:
The condition states that if Select or your dropdown field is equal to Option 1 or your options in dropdown menu whatever value the your dropdown or select field has it will be passed to the field named as "Hidden". Make sure to check "Add field to equation as text by default" so it will be text and not numbers.
