Hi Tim,
Yes, you're correct by using that function (P() = Possible). You can even use the following:
=avg({1<TYPE=P(TYPE)>} SCORE)
Kind regards,
Michel
PS: Some more examples from the documentation of this function:
sum( {$<Customer = P({1<Product={‘Shoe’}>} Customer)>} Sales )
returns the sales for current selection, but only those customers that ever have bought the product ‘Shoe’. The element function P( ) here returns a list of possible customers; those that are implied by the selection ‘Shoe’ in the field Product.
sum( {$<Customer = P({1<Product={‘Shoe’}>})>} Sales )
same as above. If the field in the element function is omitted, the function will return the possible values of the field specified in the outer assignment.
sum( {$<Customer = P({1<Product={‘Shoe’}>} Supplier)>} Sales )
returns the sales for current selection, but only those customers that ever have supplied the product ‘Shoe’. The element function P( ) here returns a list of possible suppliers; those that are implied by the selection ‘Shoe’ in the field Product. The list of suppliers is then used as a selection in the field Customer.
sum( {$<Customer = E({1<Product={‘Shoe’}>})>} Sales )
returns the sales for current selection, but only those customers that never bought the product ‘Shoe’. The element function E( ) here returns the list of excluded customers; those that are excluded by the selection ‘Shoe’ in the field Product.
