 The «lhs» expression specified in NlpDefine returned a non-numeric value when evaluated
 during the optimization.

As stated in the error, the «lhs» parameter passed to a NlpDefine function needs to evaluate to a numeric value, but did not evaluate to one.

Correct the «lhs» parameter passed to the NlpDefine function to resolve this problem.

-You have passed an unrecognized parameter to the '''Parameter''' parameter to an optimization function (E.g. [[LpDefine]], [[QpDefine]] or [[NlpDefine]]).
-You can use the [[SolverInfo]] function to display all the '''Parameter''' that can be tweaked for an engine and also the valid ranges for the parameters. The following code displays all the settings and the range for the Linear and Quadratic engines. <br>
-<code>Solverinfo(item: ['Settingnames',  'Minsetting', 'Maxsetting'], engine: 'LP/Quadratic')]</code>
