Error message

Syntax error at line 1 while checking Fuel_cost:

= Fuel_price * Mpy / Mpg

Expressions don't start with an = like they do in some spreadsheets. Just write your expression, for example write A+B, not =A+B.

Description

If you have just moved to Analytica from Excel, you may have assumed that a formula needs to have an equal character in front of it. This is unnecessary in Analytica, and it fact is a syntax error. You should just type your expression with no special prefix. The expression attributes like Definition, OnClick, etc. already expect an expression.
