You should be careful to use integer (or perhaps unsigned) consistently;
When using integers, you should specify ranges (otherwise support for full 32-bit values will be generated! during synthesis)

I think this is what was intended: (Obviously I didn't do any testing for correctness, only made necessary minimal changes to get it to build)

Also, that big addition chain is likely to give pretty lousy performance!
In general, (w+x)+(y+z) is likely to get better performance then w+x+y+z.
