LARTC - Aug 2004 - URGENT HELP needed!! Problem with second route dual ISP

Below is a snippet from my firewall script 
isp1_ip="xx.0.5.20" 
isp1_gw="xx.0.5.1" 
isp1_net="xx.0.5.0/28" 
isp1_if="eth2" 
	isp2_ip="xx.182.19.88" 
	isp2_gw="xx.182.19.1" 
	isp2_net="xx.182.19.0/28" 
	isp2_if="eth3" 
	lo_ip="127.0.0.1" 
	lo_if="lo" 
	lo_net="127.0.0.1/8" 
	ip rule delete from $isp1_ip 
	ip rule delete from $isp2_ip 
	ip route delete table 5 # isp 1 
	ip route delete table 7 # isp 2 
	ip route del default via $isp2_gw dev $isp2_if 
	ip route flush cache 
	#ip route default nexthop via $isp2_gw nexthop $isp1_gw 
	#ip route add default nexthop via $isp2_gw dev $isp2_if weight 2\ 
	# nexthop via $isp1_gw dev $isp1_if weight 1 
	echo "Adding routes ..." 
	ip route add $isp1_net dev $isp1_if src $isp1_ip table 5 
	ip route add default via $isp1_gw table 5 
	#ip route add $lan_net dev $lan_if table 5 
	#ip route add $isp2_net dev $isp2_if table 5 
	#ip route add $lo_net dev $lo_if table 5 
	ip route add $isp1_net dev $isp1_if src $isp1_ip 
	ip route add $isp2_net dev $isp2_if src $isp2_ip 
	ip rule add from $isp1_ip table 5 
	ip rule add from $isp2_ip table 7 
	ip route add $isp2_net dev $isp2_if src $isp2_ip table 7 
	ip route add default via $isp2_gw table 7 
	ip route add $lan_net dev $lan_if table 7 
	ip route add $isp1_net dev $isp1_if table 7 
	ip route add $lo_net dev $lo_if table 7 
	ip route add default scope global nexthop via $isp2_gw dev $isp2_if
\ 
	weight 200 nexthop via $isp1_gw dev $isp1_if weight 1 
	ip route flush cache 
	echo "Starting firewall ..." 
	mail/http connections to $isp1_ip fails. Why is this? 
	I want to be able to connect to both ISP and fail over to ISP1 when
ISP2 is down. 
	Thanks
