Critical update made to Lab 1a (ADA version for visual impairment only)

We just updated only the ADA version of Lab 1a (for visual impairment) with a critical fix for Spring. Here is a direct link to the newly updated file.

If you are distributing the ADA version to your students, please make sure they get this update before starting 1a.

There is no update currently needed for the standard (non-ADA) version of 1a (since last update in October).
