Error message in .lua script. Please help!

I have recivede this error message:

13:53 XenoScript Error:
Script: MistrockGround_StusseDezzie.lua
Line #: 29
Chunk: ...ents?XenoBot?Scripts?MistrockGround_StusseDezzi e.lua
Error: 'luaGetWeaponSlotData' called with invalid number of arguments [1 supplied, 0 required]!
This is an error with user-input and should not be reported as a bug with XenoBot.

I've tried to understand what's wrong but haven't figured it out. It's the .lua script that bugs and makes it unable to bot. So if anyone could just check it out for me I would be very pleased. The script is this one: http://forums.xenobot.net/showthread.php?2288-_____Stusse-amp-Dezzie-%A9-Script-Thread-_____&p=28308&viewfull=1#post28308

An argument is being passed when you need to have an empty parameter list. Please paste line 29 of the code for more help.

28. elseif (labelName == "check2") then
29. if (Self:Weapon().count < SpearsToHunt) then
30. gotoLabel("forgott")

Here you go, and thanks in advance!

Self.Weapon().count
not Self:Weapon().count
