Avogadro and GAMESS-US

Hello, I am trying to use Avogadro 1.0.3 and GAMESS to generate transition
energies and oscillator strengths to generate UV-Vis spectra. What
functionality should the “Compute…” button in the GAMESS submenu have?
For me it has no effect. Should this link to a specific command? I have
previously been using Gabedit to run GAMESS calculations from my computer,
so I know that it is all installed correctly.
Any help would be greatly appreciated.
