Newbie functions question

[LaundroMat]

Hi,

Suppose this function;

function list_champs ($running = true, $limit = 10, $order = "START_DATE")
{
// code...
}


Why then does
list_champs(false, 10, "START_DATE");
give no errors and
list_champs();
produce an error?

It works now, my function code had some errors in it.
