Unable to Access Hidden Fields in Logic Settings

I am currently experiencing an issue with my Typeform logic settings.

Specifically, I have created hidden fields (score_a and score_b) and need to use them for branching and calculations based on user responses. However, when I try to set up the logic for a question, the hidden fields do not appear as selectable options in the logic settings interface.

Here is what I have done so far:

1. Created the hidden fields score_a and score_b.
2. Verified that the hidden fields are correctly set up in the form settings.
3. Attempted to configure the logic settings for a specific question to update these hidden fields.

4. 

    

Despite following these steps, I am unable to see the hidden fields in the logic settings dropdown. I have also tried refreshing the page and logging out and back in, but the issue persists.

 I need to use the hidden fields in the following way:

• Increment score_a by 1 if a specific option is selected.
• Similar logic for score_b based on another condition.

I would greatly appreciate someone’s guidance on how to make the hidden fields visible and usable in the logic settings.
