Help with Aggregating multiple inputs

Can anyone help me find the bug in this coding?
My students are entering 2 proportion inputs on slide 2.
I’ve aggregated both inputs into separate numberlists, joined the lists in the graph, and plotted the dotplot of the joined lists. However, the graph plots each student’s inputs in a separate row of the dotplot instead of stacking the dots as would be normal in a dotplot.

Maybe because your bin width is 1, instead of 0.1 or 0.05? Honestly not that experienced with dotplots.

That fixed it. Thank you soo much!
I knew it had something to do with the fact that they were entering proportions, but could not figure out for the life of me how to fix it.
