Question: Error, invalid input: subs received fsolve

I'm trying to solve this set of two equations forn where (EQ1 and EQ2 are already défined in fontions of the followings variables (k, wr ,R,Pi), and i'm using the following loop 

eqns:={EQ1,EQ2}:

for i from 1 by 1 to 101 do R:=(i-1):S:=fsolve((eqns), {k, wr},{k=0..10,wr=0..10} ):v(i):=(subs(S,(wr))):w(i):=(subs(S,(k)))end do:
Error, invalid input: subs received fsolve({-0.6391108652e160*k+0.2384499927e160*wr+0.714075224e160*k^3-0.4729440685e160*wr^3-0.4025871558e160*k^5+0.1700629083e159*wr^5-0.4813673552e156*k^9+0.1033594302e160*k^7-0.1044324938e156*wr^7-0.1017755535e159*k^3*wr^4+0.2163976160e160*k^5*wr^2-0.7986601863e160*k^4*wr-0.2729449277e160*k^6*wr+0.8693579523e154*k^3*wr^6+0.4453377949e156*k^4*wr^5-0.2636332727e157*k^5*wr^4-0.5817233940e157*k^7*wr^2+0.5719400327e157*k^6*wr^3-0.2875232976e161*k^2*wr+0.2294793648e161*k*wr^2+0.1483050053e158*k^2*wr^5-0.3944893217e159*k^4*wr^3-0.464413477e159*k^2*wr^3+0.2760407324e157*k^8*wr+0.8238787577e156*k*wr^6-0.1081920595e...
 

i do get a solution for Pi/2 and Pi/3 but beyond this value i get the above error
