lesson-9 error in remix about VRF

[TimeKeyRoll]

When i click on green and I get this red error instead of metamask poppin. I just am trying to connect these two. yes i am connected to injected Provifder

About below screenhot

And I am not sure where this 248 is comin from. Patrick video has this number and they were using rinkeby account. since I'm using goerli this number should be same or different? And what is this all about?

@MasterofBlockchain : 248 is the VRF subscription Id , you have to put your own sub Id

Sweet and where do i get my own sub Id ?

[RoboCrypter]

@MasterofBlockchain : Go to https://vrf.chain.link/ and make your sub Id

[RoboCrypter]

@MasterofBlockchain : And then you have to register your deployed contract in the subscription you made, and then it will work.
