You have placed an alignment tab character '&' in the wrong place. If you want to align something, you must write it inside an align environment such as \begin{align} … \end{align}, \begin{tabular} … \end{tabular}, etc. If you want to write an ampersand '&' in text, you must write \& instead.

I can't figure out why you would want to use a tab mark
here. If you just want an ampersand, the remedy is
simple: Just type `I\&' now. But if some right brace
up above has ended a previous alignment prematurely,
you're probably due for more error messages, and you
might try typing `S' now just to see what is salvageable
