Example error message
Lexical error at line 6 while checking: taxTable[taxTableField='rate, incomeThreshold=incomeLevel] Text literal is missing the closing quote (') character. Do you want to edit the Definition of Marginal_tax_rate?
A literal text value must be surrounded by matching opening and closing quotes. It can be surrounded either with single quotes, such as 'rate' , or it may be surrounded with double quotes such as "rate" . However, if you forget the closing quote, or if the closing quote doesn't match the opening quote, this error occurs when Analytica attempts to parse the expression.
Press Edit Definition and insert the closing quote.
