Max 5 and connecting expr / polynomial to scope tia sal2

Greetings all

I'm trying to combine an expression with scope to view and play the waveform

an equation example I'm using is y(t) = A*sin(b*(x-c))+d I used the expr command expr $f1 * sin ($f2*($f3-$f4))+$f5 and connected it to the scope but nothing came back. I've looked at the examples for scope and expr but MAX 5 doesn't have any examples showing how to to connect a expr to a scope. Can someone point to an example.

PS: What I'm trying to do:
I have several equations using sin, cos and some in polynomial form that I would like to play using max and also see the waveform in realtime.

If you really want to see the Polynomial I'm using here it is but I'm just looking for someone to point me to an example.
