I am uploading data into the Level 1 Practice model for lesson 8.3.2 and am having trouble mapping dates- the format I am using is showing invalid, even thought I have selected the periods>YYYYMM format.
Any troubleshooting ideas would be appreciated!

You've almost got this. Everything in your mapping is correct.
Make sure your model calendar has at least 1 past year, like this.
