Why does my model upload but not produce any code blocks?

Check out the article How do I know if my Excel model upload worked

This could be due to a couple of reasons. Most likely, there is an error in the Excel upload which could include (but is not limited to): using equations in an "IF" statement or referencing a row below the row where an equation is declared. 

The best practice is to use the upload template and make sure each row where data is located also has the error handling information from column O (only the first 50 rows are handled by default within the template). 

If there are no errors, Column O will be blank. If there are, a message will display in the row where the error is located with information on what is wrong.
