Error message "Special function must be evaluated by the Excel Interpreter"

If you attempt a solve through the Solver App and receive the following error message at the bottom right of the App:

This means there is an "Excel specific" function implemented into your model that our App does not know how to evaluate. Examples of these functions are COVERIANCE.P, HYPERLINK, and INFO. This is not a comprehensive list, but may help give you an idea of what to look for in your model.

Generally, "generic" functions that do simple calculations or checks such as SUM, IF and SUMPRODUCT are not an issue.

If you unable to locate the problematic function(s) please contact our support team via email to support@solver.com, if possible include the workbook that is exhibiting the issue and we'll do our best to help investigate.
