We consider a nonlinear Dirichlet problem driven by a weighted (p,q)(p,q)-Laplacian plus an indefinite potential term. The reaction is superlinear. We prove a three solutions theorem providing sign information for all of them (positive, negative, nodal). The nodal solution is produced using flow invariance arguments.
