Parameters

Parameter	Description
other	The path of the element to compare against — see Referencing Other Elements.

Behavior

How size is measured depends on the element type:

• String — the character count
• Numeric — the numeric value itself
• Array — the number of items
• File — the file size in kilobytes

While the referenced element is empty and not yet validated, the rule passes — the comparison only kicks in once the other element has been validated or the form is submitted.
