Thanks for your response. I actually got it working perfectly, I just basically used the Custom Fields Dropdown and set the sample value to 1II1 Bedroom, 2IIBedroom and so on..
I left the “Any Amount of Bedrooms”‘s Value as IIAny Bedrooms.
I am not sure if the above makes sense, but it seems to work by leaving this as a default it displays every property regardless of number of bedrooms.
Thanks for your response,
