Killzone script error (I'm new to both coding with gd-script and coding overall + making games)

Godot Version

Godot_v4.6.2-stable_win64.exe

Question

I'm trying to "code" a simple killzone to trigger a signal for the player to be removed from the scene. My code for the player ("characterbody2d") has no errors but the issue arrives in the killzones code's mixed use of tabs and indentations!

Here’s a reference pic:

I’m open to tips, replacements and etc.

Thanks for the help!
