Hi, I can't get my mod20 sequential circuit to work, the output keeps showing xxxxx. I'm using Quartus ll 8.1 web edition

I have managed to get it to work on breadboard with hardware so I'm guessing my logic is correct but i'm new to Quartus and could do with a few pointers to why I cannot get any output from my circuit...

The code you've generated from the schematic is Verilog code but your errors are VHDL errors. The compiler is, for some reason, trying to compile this Verilog code as VHDL code.

Do not edit the code at all. It looks like your filename has a .vhd extension instead of .v. Change it to .v since this is Verilog code. Then follow the rest of Khai's instructions.

    Ok so I changed it to .v but it still gives me errors?
