# [NTG-context] Insufficient symbol fonts

Hi,

preparing a presentation, I am into errors like

! Math formula deleted: Insufficient symbol fonts.
l.67                    \symbol[psi]\low{\tfx{\it i\/}+1} $-$
120,

again and again.
Admittedly, my font knowledge is probably the worst of my tex skills.

Is there a way to increase the number of available symbol fonts? A quick
hack would do, since I am kind of under pressure...

Thanks,
Eckhart
