Calc Use Cases

Count the Items in a Collection List

Preparation;

• Setup your Collection List

• Create the element where you want the Collection List count to appear

Attributes;

Choose a unique name for the items you're counting, we'll use test1 for this example.

On the element that will display the count;

• Add the wfu-calc = count attribute

• Add wfu-calc-source = test1 attribute

On the collection list;

• Place wfu-calc-field = test1 directly on the Collection List Item element.

If you have more than 100 items to count, you can use multiple collection lists each ranged to show 100 items from your collection. Assign the same wfu-calc-field = test1 to each and they will all be counted together.

Sum the Values within a Collection List

Preparation;

• Setup your Collection List

  • Within the Collection List, place your element which contains the value you are wanting to sum

• Create the element where you want the Collection List sum to appear

Attributes;

Choose a unique name for the items you're counting, we'll use test2 for this example.

• Add the wfu-calc = sum attribute

• Add wfu-calc-source = test2 attribute

On the element within your collection list that contains the value to be summed;

• Place wfu-calc-field = test2 directly on the Collection List Item element.

If you have more than 100 items to count, you can use multiple collection lists each ranged to show 100 items from your collection. Assign the same wfu-calc-field = test2 to your data within each and they will all be counted together.
