Variable Tool
Variables are used to store values. It is typically used as a container for a result that changes after an expression or look-up operation. Use it to set a temporary field that will hold a value only for the current record.
Variables can hold data values as a result of a user's answer to a question (their age, for example). In the sample below, the constant value is passed to a variable and then compared with input provided by a user on an associated web page.
