I have set this up before with no trouble, now I cant set up my paypal account(sandbox) on flynax because for some reason I can't find the merchant ID, which I think they have changed the name from merchant ID, But I still can't find the ID that is required.....

Any help members puttiing me on the right track..I might have to walk away, have a coffee and try again at a later date moment !!

Cheers
