Defining a custom web addressThe web address for a web viewer is a calculated expression, similar to a formula specified by a calculation field. To create a custom web address, you create a formula that can consist of constants, field names, functions, and operators. FileMaker Pro evaluates the expression to construct a URL, which the web viewer uses to display a web page.
