Question

I have "name" JavaScript variable. If variable "name" contains less than 4 characters I want to execute line: msg('name','Your name must contain minimum 4 characters.')'; I have tried something like this but it interpretated mathematical. Any idea? Thank you.

  msg('name','Your name must contain minimum 4 characters.');
  return false;
}
