Frame Relay down

I'm practising in my lab with frame relay multilinking but I'm having a lot of problems on R2 which has 2 serial connections to the frame relay switch. Line protocols stay down. I tried another frame relay switch, I still got the same problem. I have change NM-4T, to NM-4AS and NM2W-1FE with 2 serial cards, no joy. The serial on the frame relay router is the 7th. The first serial interface on R2 comes and stays up without any problems. All other routers from R1 to R6 interfaces are up except the second on R2 which I'm talking about.
If I change this particular interface encapsulation to PPP, it stays up, Immediately I configure frame relay encapsulation on it, it goes down.
I've tried both cisco 2522 and now cisco 2611XM with NM-8A/S
clock rate on the frame router is 64000 and have lowered it several times with the same result.
R2 is a 3640 with NM-4A/S.

Anyone knows what I'm doing wrong?

Put a show run output on the site and We'll take a look

double post, but I will give it a shot...
on 1/6 on the frame switch your missing frame-relay intf-type dce...then your frame routes look a bit off

Im also thinking your R2 is connected to Frameswitch 1/6?

Thanks, you spotted it well. I've spent about four hours on this. What do you thing is wrong with the frame relay route?
Thanks
