Hello, I am writing a verilog code from my DE10-Lite Board to scroll the a word or number but keep having errors. Would you be able to help?

I get different errors than you did when elaborating this code. However, you have "sseg" but never define it. It should be type reg. You also make assignments to HEX_Display in two separate processes. I think you mean for HEX_Display to be on the right side of the final assign statement:

assign {g,f,e,d,c,b,a} = HEX_Display;

And since HEX0-HEX3 are single bit inputs, making sseg a single bit value, only the 0 and 1 checks in the final case statement can match to set the value of HEX_Display. This only displays warnings, not errors, when compiled but it should be fixed.
