how can I add in a static price list by product to calculate depending on the amount put in the table?

To clarify, do you want to use the INPUT table to calculate values?

You may use conditions to calculate the values in the input table.

However, if this doesn't fit your requirements can you please explain further your question regarding static price?

Can you please also share your form?

Looking forward for your response.
