And I expect the OP wanted the symbol \displaystyle \begin{align*} \phi \end{align*} or \displaystyle \begin{align*} \varphi \end{align*} or \displaystyle \begin{align*} \Phi \end{align*}.

Wiggle the cursor over the symbols for the code :)

Thanks so much to Plato and Prove It for the help. I was copying code from a post and couldn't get it to work using [tex] tags. When I saw you used [TEX] I tried it and it worked.

Now to reply to hacking post to put it back on top. Im also having problems.
