dear all,

i wrote this process and i get allways error:241:15:241:15|Expecting expression

my question how can i fix that and what is the mistake?

proc_Ram_Map: process(Ah, downloading , RD , WR ,HW, SWdog_Rst )

begin
A16_F <= '0';
FlashRD <= Psen;
FlashWR <= '1';

if ((Ah =< "01000000" and downloading = '0')and ((WR'event and WR='0')or(RD'event and RD = '0'))) then
FlashRD <= RD;
FlashWR <=WR ;
A16_F <= '1';
end if;
end process;

thanks you all in advance.
