[quote=@rush99999]Were we supposed to roll for starting wealth? Because I've just had a look at the other characters and I'm fairly certain I'm the only person who rolled for starting wealth.[/quote]
You only roll for starting wealth if you don't accept the standard equipment awarded for your class and background. After rolling you then have to use some of your wealth to purchase weapons, armour and equipment you want to take with you. If you do choose to take the standard equipment then you should only start with the amount of money stated in your background description.

As an example, for Rogues the rules state:[quote=Player's Handbook, page 96][color=silver][i]You start with the following equipment, in addition to the equipment granted by your background:[indent](a) a rapier or (b) a shortsword
(a) a shortbow and quiver of 20 arrows or (b) a shortsword
(a) a burglar's pack, (b) a dungeoneer's pack, or (c) an explorer's pack
Leather armor, two daggers, and thieves' tools[/indent]Alternatively, you may start with 4d4 x 10 gp to buy your own equipment.[/i][/color][/quote]And Entertainers start with:[quote=Player's Handbook, page 130][color=silver][i][b]Equipment:[/b] A musical instrument (one of your choice), the favor of an admirer (love letter, lock of hair, or trinket), a costume, and a belt pouch containing 15 gp[/i][/color][/quote]
This means a Rogue Entertainer could either start with:[indent]2 shortswords, burglar's pack, leather armor, two daggers, thieves' tools, a musical instrument, an admirer's favor, a costume and 15gp[/indent][center][i][b]or[/b][/i][/center][right]4d4x10gp with which to purchase everything.[/right]
Also, if you take the standard equipment you may spend some of the money granted by your background to purchase additional gear prior to joining the campaign. The DM might want you to come up with a plausible reason why your character may be carrying some items though, if you choose something unusual or which would conflict with your character's background and class.
