  We consider recurrent solutions of the nonautonomous modified Swift-Hohenberg
equation $$u_t+\Delta^2u+2\Delta u+au+b|\nabla u|^2+u^3=g(t,x).$$ We employ
Conley index theory to show that, if the forcing $g:\mathbb{R}\rightarrow
L^2(\Omega)$ is a recurrent function, then there are at least two recurrent
solutions in $H_0^2(\Omega)$ under appropriate assumptions on the parameters
$a$, $b$ and $g$.
