A Bootstrap-4 template for Zen Cart versions 1.5.8 through 2.1.0. Forked from https://github.com/zcadditions/ZCA-Bootstrap-Template-for-1.5.6-v2.0.0c. See the demo site, below, for additional information.
I ran the shopping cart through a WCAG tool (WAVE for Chrome) and kept getting this error message about a broken ARIA reference and tracked it to this.
Fixing mislabeled id for WCAG purposes. (Was still labeled as exampleModalLabel.)
