TOPIC: conditional custom fields NG with Google Chrome Apple Safari

Again, thank you for your ingenuity with this component. It is powerful and complex, as I know you realize.

That being said, I watched the tutorial video and have laid out a simple conditional custom field according to the video details; inclusive of selection limits.

However, during test of the options on my event scenario; the Normal Custom Field is shown properly, yet the Conditional custom fields are not shown/evident on the following browsers: ONLY Google Chrome, APPLE Safari.

Firefox/Flock browser(s) show the conditional field perfectly during the test.
I am a MAC user and have installed the NEWEST component version.

Comments? Thoughts?
