can anyone figure out why the hell this table isn't compiling? I swear it worked fine a few weeks ago and I haven't touched it since. But now....

never fails.... as soon as I make a topic, I figure it out myself.
I turned the multicolumn lines into:

          & \multicolumn{3}{|c|}{$C_{L_{\delta_f}\alpha}$} & \multicolumn{3}{|c|}{$C_{m_{\delta_f}\alpha}$} & \multicolumn{3}{|c|}{$C_{l_{\delta_f}\alpha}$} \\ \hline
          Effector & Slope & Int. & $r^2$ & Slope & Int. & $r^2$ & Slope & Int. & $r^2$ \\ \hline
