I have the following set up in Packet Tracer:

enter image description here

I am trying to configure frame-relay between the RTR-EDGE router, the RTR_ENG router and the RTR_SAL router using a frame-relay switch simulation (the cloud). I have used the following commands:

RTR_EDGE(config)#int s3/0
RTR_EDGE(config-if)#encap frame-relay
RTR_EDGE(config-if)#frame-relay map ip 172.20.1.109 101 broadcast
RTR_EDGE(config-if)#frame-relay map ip 172.20.1.113 102 broadcast
RTR_EDGE(config-if)#ip address 172.20.1.117 255.255.255.252
RTR_EDGE(config-if)#frame-relay lmi-type cisco
RTR_EDGE(config-if)#no shutdown

RTR_ENG(config)#int s0/0
RTR_ENG(config-if)#encap frame-relay
RTR_ENG(config-if)#frame-relay map ip 172.20.1.117 200 broadcast
RTR_EDGE(config-if)#ip address 172.20.1.109 255.255.255.252
RTR_ENG(config-if)#frame-relay lmi-type cisco
RTR_ENG(config-if)#no shutdown

RTR_SAL(config)#int s0/0
RTR_SAL(config-if)#encap frame-relay
RTR_SAL(config-if)#frame-relay map ip 172.20.1.117 200 broadcast
RTR_SAL(config-if)#ip address 172.20.1.113 255.255.255.252
RTR_SAL(config-if)#frame-relay lmi-type cisco
RTR_SAL(config-if)#no shutdown

And the circuit appears in the map of each router:

RTR_EDGE#show frame-relay map
Serial3/0 (up): ip 172.20.1.109 dlci 101, static, broadcast, CISCO, status defined, active
Serial3/0 (up): ip 172.20.1.113 dlci 102, static, broadcast, CISCO, status defined, active

However, neither of the three routers can ping each other? Does anyone have any ideas as to why not? I have looked at a few tutorials on the internet and their commands are the same as mine, however theirs works and mine doesn't..

Any help would be appreciated! Thanks

Do you have the routes to each other router?

I don't know if it is necessary to add the routes to your frame-relay configuration, but you should check like this:

RTR_EDGE# show ip route 172.20.1.109
RTR_EDGE# show ip route 172.20.1.113
RTR_ENG# show ip route 172.20.1.117
RTR_SAL# show ip route 172.20.1.117

Your endpoints are on a different subnet to each other, if you decrease the subnet mask to a /27 (255.255.255.224 in non-CIDR terms) you should have more luck.
