Use loop for with if

[Altera_Forum]

In my architecture I put a loop for, and I want when my index = 1, switch on my led 1,  

but for others switch them off, maybe this is a stupid error, but myfollowing code is wrong the error comes from line : if (i = 1) then, please anyone could help me ?  gene_led: for i in 4 downto 1 generate  process(init,opg_clk)  begin  if (i = 1) then  led(i) <= '0';  else  led(i) <= '1';  end if;  end process;   end gene_led;

I didn't defined led as a signal but as a variable that's why it couldn't work :p
