I ran into an issue with my Firefox browser. Firefox displayed the “string accumulate” options, but didn’t always display the “Array Reduction” options. I used Microsoft Edge browser to do the Text Chart lab


Hi John,

I’m not entirely sure this is a browser issue - could you please post a screenshot of your browser view when you try to find the “Array Reduction” option? Thanks!
