 Description

In the example shown here, the math region is evaluated numerically (by typing =). The error message says I.160 not defined. In fact, it is t which is not defined. This is confusing and costs you time when debugging sheets.

Investigation results from description are correct.

The issue is about detecting position of the undefined variable/function in the equation when calculation performed right after definition.
