Error message

I do not understand why I am getting the error message for the code below.... Error (10818): Netlist error at up_dwn_counter.vhd(61): can't infer register for d_o[0] because it does not hold it...

You need to think about what hardware you want to generate. A register is only sensitive to 1 clock edge, either rising or falling so if you remove the section of code that checks for the falling edge of cl then you should be ok.
