Resolved Adding a Public Function to an Event

Hi, I have a function from a script that I'm trying to add to an event from a different script. I've looked at some similar posts and had no luck there.
This is the function:

Code (CSharp):

1. public void Onlanding ()
2.     {
3.         animator.SetBool("IsJumping", false);
4.     }

Screenshot of the event dropdown:

Apologies if I've left something out or not shown something as I'm a first-time poster and new to unity.
Thanks in advance for any responses

EDIT [SOLVED]: It's fixed now. For whatever reason, Unity wasn't showing me some compiler errors in a different part of the script. After a restart and a few edits, it displayed the function in the dropdown where I expected it. Thanks for all responses so far.

 

Which script is the Onlanding function you shared here on?

 

It's in the PlayerMovement Script

 

can you confirm the class name and the name of the file containing "OnLanding" method is the same ?

any errors in the console ?

 

Not quite sure what you mean by class, sorry. I can tell you that all of the names/capitalization and similarities are all the same across everything. Also no, there are no errors in the console either.
