Steps:

1. Add GetChatTypeIndex
2. Set arguments to "RAID"
3. Press the function in list to execute
4. Observe return value

Expected: 4 (as reported by /dump GetChatTypeIndex("RAID"))

Actual: 0

Screenshots:

Yeah, ty for reporting. It's just a problem with not intuitive/not standard and badly documented arguments console.

You don't have to use quotations for strings right now:

"RAID" should be just RAID in console

Will have to update this when i have time and figure out some standard way to use this.
Cant fix right now.

Ah, I see. Quite confusing given how it's formatted.
