Why am I unable to upload my Excel files in the Mission Center?

During uploading my Excel activity templates, sometimes some error messages are displayed : this means that inconsistencies were discovered and have to be resolved to be able to upload them. 

First situation: characters excess

The most common error message may concerns the characters excess. Indeed, when you fill your Excel activity templates, it is important not to exceed the characters limit, provided in the Instructions sheet (and / or in the columns title).

Second situation : specific errors regarding activities

You can encounter other kinds of errors during the Excel activity templates uploading, which will concern specific activities. In that case, when you create a testing version of your training in the Mission Center, a clear error message is displayed. This message includes: 

• the activity template language which contains errors 
• the activity ID, i.e., the line to change in the Excel activity template

Note: The above mentioned problems are the most common ones, however you may encounter another problem, and then contact our teams at support@teachonmars.com
