Lua : return table trough function is nil

Question

I get the error: source_file.lua:5: attempt to call a nil value (global 'getCard')

i try to catch the right table in questCards which Index=name is the same as the given string from objName

questCards={{['name']='test1',['creatureName']='test3'},{['name']='test2',['creatureName']='test4'}}
obj='test1'
card=getCard(obj)
card['creatureName']=nil --Only for test purpose
if card['creatureName']==nil then
    --do Somthing
end
function getCard(objName)
  for k,v in pairs(questCards) do
    if v['name']==objName then
      return v
    end
  end
end

As Ihf has said, you're calling the getCard() function before you've defined it, so you need to move the function up above the call to it in the file. — TheAverageCanadian

The error message is telling you that getCard is not defined at the point where it is called.

You need to define getCard before calling it.
