Conditional Expression Builder
The Conditional Expression Builder allows you to associate an expression that references one or more fields in the table with a display statement (in Xdialog syntax) that may contain static text, text computed from table fields, any type of font formatting, buttons, and images. You compose the display statement interactively. You have have multiple expressions that apply different display statements for different conditions. Alpha Anywhere uses the first condition that satisfies the expression and ignores any other conditions that may also satisfy the expression. For example, if you have the following expressions and the lastname field contains the value "Pierce".
You do not need to know anything about Xdialog to use this utility.
