Lua Index Expected, got function

Question

The data variable is a parameter in a function. sheeple is an instantiated table. I printed out the type of id and data which printed "number" and then "string" respectively. However, upon the execution of sheeple[id]=data, I get the error "index expected, got function." Thank you for any help.

    local id = 0
    local tmp  = data:sub(8)
    tmp = tmp:sub(1,tmp:find("[^0-9]")-1)
    id = tonumber(tmp) 
    queue(id)
    print(type(id))
    print(type(data))
    sheeple[id]=data

Could you provide some more info? Is there any other value called id, which is a function(just a guess)? Do you have a backtrace? — Uncle Dino

There are no other variables by the name of id at all. I am not sure what a backtrace is. — Even Pardides

It seems that sheeple is doing something especial with indexing. Look at its metatable, especially the __index and __newindex methods. — lhf

Upon further review of my code. Embarrassingly, sheeple was also the name of the function that the code segment was in.

Can a moderator close this question? I am not able to accept my own answer after two days.

I thought so as well, but upon capitalizing the table value's name the error went away.
