Mobile Form Expression Log Messages

The Mobile app can log when an expression is registered, when it returns a value, and when parsing or evaluation fails.

Log Entry	Description	Example Invalid Expression	Example Log	Resolution
Initialization	The message identifies the target property and its dependencies.	-	BIND INIT area value { width: ["value"], height: ["value"] }	-
Successful Evaluation	Valid expression	(width.value || 0) * (height.value || 0)	BIND INIT area value { width: ["value"], height: ["value"] } BIND SET area value 0	-
Parse Errors	A parse error means the expression is not valid JavaScript.	(width.value || 0) x (height.value || 0)	BIND PARSE ERROR area value SyntaxError: Unexpected identifier	Replace the invalid operator with an asterisk (*).
Runtime Errors	A runtime error means the expression was parsed but failed when it ran. Element names are case-sensitive.	(width.value || 0) * (HEIGHT.value || 0)	BIND RUNTIME ERROR area value ReferenceError: HEIGHT is not defined BIND SET area value undefined	Element names are case-sensitive. Replace HEIGHT with height.
