I am getiing an error :
The undeclared "1" is not an index.
I am on the declaring identifiers portion of the course building my 1st AIMMS app.

‘1’ is a numerical value, and can not be an index. An index is typically a letter. For example a set called Customers has an index ‘c’ after which you can create a parameter Demand over the index ‘c’: Demand(c).
Hope this helps.
