**EltonCris**Hi,

Am I right that you want to fill a value on some specific column of the matrix field that can' t be edited? Unfortunately, it's not possible with the matrix table in the form builder but you can take your form source code and apply a constant value. http://www.jotform.com/help/104-How-to-get-the-Full-Source-Code-of-your-Form

There is actually a workaround by prepopulating values on the matrix field but this is editable on the form. http://www.jotform.com/help/71-Prepopulating-the-fields-to-your-JotForm-via-URL-parameters

Let us know if you need further help. Thanks!
