I forgot to the British accent during the first round of auditions: need I be worried?

I forgot to do the British accent during the first round of auditions for a series: need I be worried? I can do it, but I just forgot to do it out of nervousness. Will this affect the panel's decision on whether or not I'll get a callback? Or, are they just looking at the acting aspect at first, and at the second round of auditions ask me to do the required accent? I'm very worried.

.. if the accent is required and you failed to do it.. you have failed to complete your audition. If your acting surpasses everyone that auditioned and your image also supported the role more then the other contestants, you may have a chance for call backs.

If not.. sorry

Good luck
