Translations:Expression Manager - quick start guide/44/en

Anything within curly braces is treated as an expression, being syntax-highlighted (color coded) in the prior image. If you have any typos (such as misspelled or undefined variable names or functions), EM would show an error. In our below example:
 * heightunit.shown is an undefined variable name (it is actually heightunits.shown) and
 * "rnd" is an undefined function (the proper function name is "round").
