I need help with an error "Undefined function or variable 'x'"

sym n x
w0 = pi; T0 = 2  ; n = 1:5;

a0 = (1/T0)*int(1,x,0,1)
an = (2/T0)*int(1*cos(n*w0*x),x,0,1)
bn = (2/T0)*int(1*sin(n*w0*x),x,0,1)

 % if true
    % code
 % end
syms n x
w0 = pi; T0 = 2  ; n = 1:5;
a0 = (1/T0)*int(1,x,0,1)
an = (2/T0)*int(1*cos(n*w0*x),x,0,1)
bn = (2/T0)*int(1*sin(n*w0*x),x,0,1)

Thanks a lot. Can't believe its just an 's' I missed after about an hour looking for the error

The first line should be:

syms n x

that is, syms with a second ‘s’. (The sym call is to a valid function, however that syntax for it is wrong.)
