Table not being recognized?

[GrimmSpector 0]

I've got a piece of code, trying to insert some values into a table, as below.

local table1, table2, table3 = {}

function somefunction(inputtable)
  for k,v in pairs(inputtable) do
    if k == "1" then
      table.insert(table1, v)
    elseif k == "2" then
      table.insert(table2, v)
    end
  end
end

I get an error referencing one of the table insert lines, like this:

extractorController.lua:34: bad argument #1 to 'insert' (table expected, got nil)
stack traceback:
    [C]: in function 'insert'
    extractorController.lua:34: in function 'somefunction'
    [C]: in function 'xpcall'
    machine:751: in function 'xpcall'
    /lib/process.lua:78: in function </lib/process.lua:71>
stack traceback:
    [C]: in function 'error'
    /lib/process.lua:92: in function </lib/process.lua:71>

Clearly I'm defining these tables at the start of the file...so I'm not sure why this is occurring...? I'd really appreciate some help figuring this out! Thanks.

local table1, table2, table3 = {}, {}. {}

 

You only defined one variable.

Ah I didn't realize lua did it that way, ok thanks!
