integral fails entering code below. Hopefully I'll avoid typos

Here is the code:
show("taken from Mahtematica")
show("G.2.a.singularity")
var('y a b q t r')
m(x,y)=q(x-a)/((x-a)^2+(y-b)^2)
n(x,y)=q(y-b)/((x-a)^2+(y-b)^2) m(x,y)=5*(x-a)/sqrt((x-a)^2+(y-b)^2)
n(x,y)=5*(y-b)/sqrt((x-a)^2+(y-b)^2)
m(x,y)=q*(x-a)/((x-a)^2+(y-b)^2)
n(x,y)=q*(y-b)/((x-a)^2+(y-b)^2)
#m(x,y)=5*(x-a)/sqrt((x-a)^2+(y-b)^2)
#n(x,y)=5*(y-b)/sqrt((x-a)^2+(y-b)^2)
