@moonday For now you can use the filter
formula function to achieve the same effect. For example you could create a formula field with the formula:
filter(
lookup('Assets in Room', 'Price'),
or(
totext(lookup('Assets in Room', 'Asset Type')) = "Chair",
totext(lookup('Assets in Room', 'Asset Type')) = "Desk")
)
Its more complex unfortunately than the filter builder method suggested which we do want to add, but hopefully helps for now. I also invited you to a Baserow workspace I made showing the above formula in action.
One advantage of the formula way is you can then aggregate the results like so:
sum(filter(
lookup('Assets in Room', 'Price'),
or(
totext(lookup('Assets in Room', 'Asset Type')) = "Chair",
totext(lookup('Assets in Room', 'Asset Type')) = "Desk")
))
