I Need Help With A Datapack

Hi. I'm Trying To Create A Blaster/gun Datapack For Personal Use, I Used A Raycast System From (TimberForge) Along With A Carrot-on-a-stick Right Click Detection System From (Legitimoose)...
The Problem Is That I'm A Noob When It Comes To Datapacks Lol (This Is My First Time Doing Anything Related To Datapacks), Currently When A Player Right Clicks With A Carrot-On-A-Stick The Chat Says,  "Click" But No Raycast Is Shot... My Only Guess Is That The Function Doesn't Know What Entity To Fire The Raycast From, (The [tick.mcfunction] Code Is "execute as @a if score @s carrot matches 1.. run function carrot_stick_gun:start_raycast" ) Please Feel Free To Ask For Screenshots Of The Files
