I just started using Mathematica. I searched but can't solve this issue.
I'm trying to manipulate the plot of a fourier sine series.

Here's as far as I can get it to work:

fourier[b_] := FourierSinSeries[x^2/4, x, b]

Manipulate[fourier[s], {s, 1, 10, 1}]

it works perfectly, giving me the series expansion with as many terms as I want through the slider.
But when I try to plot it it doesn't work!

fourier[b_] := FourierSinSeries[x^2/4, x, b]

Manipulate[Plot[fourier[s], {x, -10, 10}], {s, 1, 10, 1}]

I just get an empty plot wih the slider.
Even if I try the simpler command:

Plot[fourier[2], {x, -10, 10}]
I get an empty plot.

I don't understand the problem because if I do this, it works:

d = fourier[2]
Plot[d, {x, -10, 10}]
