Parameters

• ATTRIBUTE: Any type of standard attribute or custom attribute (number, text, or other types).
• MIN-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 lowest value of this attribute.
  
  If you specify a text attribute, the function sorts by lexicographic order and selects items at the beginning of the sort list.

Example

An ad group that's scoped to the "MyBrand" brand contains the following items:

BRAND	TITLE	PRICE	DISCOUNT
MyBrand	Red shoes	$10.00	10%
MyBrand	Yellow shoes	$10.00	10%
MyBrand	Blue shoes	$10.00	5%
MyBrand	Crew socks	$5.00	20%
MyBrand	Dress socks	$5.00	20%
MyBrand	Knee-high socks	$5.00	15%

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

  1. Scans the PRICE column and finds the items that share the lowest price.
     In this case, the function selects "Crew socks", "Dress socks", and "Knee-high socks" (which all specify a price of $5).
  2. Scans the DISCOUNT column for "Crew socks", "Dress socks", and "Knee-high socks" and counts how many items specify the same value.

  In this example, the function returns 2 ("Crew socks" and "Dress socks" both have a 20% discount).

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