it means you're using the wrong amount of arguments for a function, for example, the function is like this:

Код:

 
function(param, param, param);

your error is that you do not define all params, or too many, either one of these:

Код:

function(param, param); // not enough params defined!
function(param, param, param, param); // too many!
