Error at endif Client (SWEP)

[ItzDannio25]

Hi everybody, I am creating a SWEP of a whistle that if you hold left will sound. When I enter gmod, I get this error:

[ERROR] lua/weapons/weapon_whistle.lua:46: '=' expected near 'then'
  1. unknown - lua/weapons/weapon_whistle.lua:0

Here I leave my script

Why this happens? anyone knows? i'm new at Lua programming.

How about you read the Error message? I went down to line 45/46 and instantly found the mistake.

You wrote end and if together. It says

endif CLIENT then

Thanks lmao, i didn't see it, sorry about that (i started learning Lua today lol)

[Trackster]

then i suggest learning lua a bit first, getting the basics, instead of doing something and then coming here as soon as theres a problem?
