I cant work this out!

This is to adjust volume of incoming audio samples by just multiplying by a constant value (SW). I wanted to be able to control the volume value with the switches on the DE2 but i get no sound at all...

One additional thing to add is the some editors / IDE's catch this sort of thing before even attempting to compile. This alleviates headaches when trying to discern if there is an actual problem with hardware. My personal favorite is the Sigasi HDT editor. I've attached an image of how it found the "multiple markers at line 65" error, because of the issue with 

sample_out<=sample reg; -- Note the space between 'sample' and 'reg'
