How to use functions in delphi?

Question

Delphi

Hello. Involuntarily, I had to deal with delphi.
I'm doing a simple test, I need to call the refresh_questions() function on certain events.
The problem is that in this function I cannot use form elements. (change label's caption)
Throws E2003 Undeclared indentifer: 'Label1'

How do I interact with form elements from within my function?

Answer 1

So you create this function inside the form class
