it is not a valid field in the table

[arsilva_2021]

Good morning my friend. I created the panel and inserted a parameter, when I use this parameter in a formula for another field it responds that "it is not a valid field in the table". How can I make this parameter part of the table? Thanks.

Hello,

Can you give me more information?

The units must be coherent to be used in a formula. For example, you cannot make a length parameter equal to an area parameter.
