Question: problelm in numerical solution of ode

when i try to solve the equation given below the following problem occured. pleae tell me how can i solve this boundary value problem.

> eq := -(diff(p0(x)*(diff(v(x), x)), x))+q0(x)*v(x) = f0(x);

> l1 := -p0(0)*(D(v))(0)-p0(0)*v(0) = 0;

> l2 := p0(1)*(D(v))(1) = 0;

> dsol := dsolve({eq, l1, l2}, numeric);
Error, (in dsolve/numeric/bvp/convertsys) too few boundary conditions: expected 3, got 2
