How do I delete a post that repeated itself?

[lloydsolutions]

My post appeared to be going to the forum when I pressed the submit button but did not appear. I resubmitted it using exactly the same wording and the same thing happened. Thinking that it was due to using the same wording twice I resubmitted it using different wording. To my horror the three posts appeared in succession and now I cannot view the forum probably due to this. How can I delete these two posts? Edit won’t allow me to do this. Your help would be appreciated.
