I can't use a custom function in Sheet

I just started with Apps Script and I'm facing an issue. I am trying to use a custom function in a google sheet but I get the error "NAME?". My guess is that Google Apps Script does not have permission to access my Sheet files. Coud anyone help me? Thank you 🙂

Solution

It works. turns out the binding wasn't done. I was trying to use a function defined in a stadalone script.
