Setting BGP weight not working

I am trying to set the weight for route 78.15.1.192/26 that Router1 learns from ISP1-R1 to 100.

I have created a prefix-list, applied it inside a route-map setting the weight, applied it to the neighbour (inbound) and reset all neighborships. But it is not working and I don't know why. Below is output from Router 1. Can anyone help?

R1#show ip prefix-list

ip prefix-list MATCH_78: 1 entries

seq 5 permit 78.15.1.192/26  <<<<<<<<<<<<matching prefix. implicit deny blocks all others.

ip prefix-list SET_METRIC_78: 0 entries

R1#show route-map

route-map SET_METRIC_78, permit, sequence 10
  Match clauses:
    ip address prefix-lists: MATCH_78  <<<<<<<<<<<<<<<matching the prefix-list
  Set clauses:
    weight 100  <<<<<<<<<<<<<<<<<<setting weight
  Policy routing matches: 0 packets, 0 bytes  <<<<<<<<<<no matches. Maybe the problem is here?

Setting BGP weight not working

Never mind! I'm an idiot. It's 4am and I am very tired.

I typed neighbor 101.101.101.1 prefix-list SET_METRIC_78 in and should have typed neighbor 101.101.101.1 route-map SET_METRIC_78 in

R1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.

R1(config-router)#neighbor 101.101.101.1 route-map SET_METRIC_78 in

I'm going to bed.
