How to Let Users Edit Formulas in Wappler?

Hello,

I am currently developing a business configurator for an industrial context, aimed at generating quotes for clients.

In this setup, I naturally have constants and business rules that I translate into formulas. So far, this part is not an issue.

However, I would like to make these formulas configurable directly within the user interface of the application, so that users can modify them if needed. This is where I am encountering difficulties, particularly due to my current level of familiarity with Wappler.

For example, a formula could be:
“The product price is calculated as length × width × 1.25.”

If, at a later stage, the client wants to change this formula to:
“length × thickness” (removing the 1.25 multiplier),

how can this kind of change be handled dynamically?

Have you ever faced this type of requirement? If so, are there any standard or semi-standard approaches to implementing this cleanly in Wappler?

Thank you in advance for your help.
