Micha,
You have to specify the argument in the brackets. (Well, I
suppose it might be possible to avoid doing so, but why go
looking for trouble?)
So, your code should look like:
function some_function($argument)
{
validate_arg($argument);
//more code
}
function validate_arg($argument)
{
//this function validates the argument of some_function()
}
