Question: Multiple function calls within Maple Addin

Is it possible to execute an fsolve() for the equation as given below? I have not been able to get it to work thus far. Thank you for your support. Excel cell formula: =Maple("fsolve(2*(2*EllipticE(&1)-EllipticE(sin(beta),&1)-EllipticK(&1))+2*EllipticF(sin(beta),&1)=tan(beta)*sqrt(1-&1^2*sin(beta)^2),beta);",I14)
