"and" statement in M Language

Hi,

I am wanting to add a and statement into my conditional form.

 #"Added Conditional Column" = Table.AddColumn(#"Changed Type", "Custom", each if Text.StartsWith([#"(Master) Campaign"], then "Remnant" else if Text.StartsWith([Advertiser], "House") then "House" else if Text.StartsWith([#"(Master) Campaign"], "1xl") then "National" else if Text.Contains([#"(Master) Campaign"], "COLUMBA") then "Local" else if Text.Contains([#"(Master) Campaign"], "BA ") then "BA" else if Text.Contains([#"(Master) Campaign"], "Amazon") then "Partnership" else if Text.Contains([#"(Master) Campaign"], "Teads") then "Partnership" else 

I am wanting to use a and statement and say something like

If Text.Contains([#"(Master) Campaign"], "House") and  Text.Contains([#"campaign"],"Open"), then "House Paid" 

then carry on with the else if

Any help appreciated.

Thanks

Chris
