Why am I getting this error?

I'm using pdepe and I keep getting the error "Error using pdepe (line 293) Spatial discretization has failed. Discretization supports only parabolic and elliptic equations, with flux term involving spatial derivative". Why is this happening?

Thanks!

This error usually occurs of your problem does not fall in the class of problems pdepe is suited for.

The problem class is defined in equations (1.4), (1.5) and (1.6) under
