  • ATTRIBUTE: Any type of standard attribute or custom attribute (number, text, or other types).
  • MAX-ATTRIBUTE: Any type of standard attribute or custom attribute (number, text, or other types), though typically you specify numeric or monetary attribute. The function selects all items that share the highest value of this attribute.

    If you specify a text attribute, the function sorts by lexicographic order and selects items at the end of the sort list.

  • In an ad template, 
    [count_with_max(DISCOUNT, PRICE)]
    does the following:

    1. Scans the PRICE column and finds the items that share the highest price.
      In this case, the function selects "Red shoes", "Yellow shoes", and "Blue shoes" (which all specify a price of $10).
    2. Scans the DISCOUNT column for "Red shoes", "Yellow shoes", and "Blue shoes" and returns the number of items that share the highest discount.

    In this example, the function returns 2 ("Red shoes" and "Yellow shoes" both specify a 10% discount).

  • In an ad template, 
    [count_with_max(TITLE, PRICE)]
    returns 1, since all items with the highest price have unique titles.
