Oscillations A level physics

The formula for velocity in an oscillation is v=-Aw sinwt

But when v is max, amplitude is 0. Therefore following the equation replacing the A with 0 would cause v to be 0. This is not the case as we know the velocity cannot be 0 here.

Can someone please explain what is happening here.

Since -1 <= sin(wt) <= 1, V is max when sin(wt) = -1

So V max = Aw.

Since -1 <= sin(wt) <= 1, V is max when sin(wt) = -1

So V max = Aw.

Thank you for replying. I am still confused how this works if the amplitude is 0 at v max. I know that when the equilibrium point is reached, the velocity is max and amplitude is 0. A does stand for amplitude here right?
