How to conditionally clear or select a checkbox option in the form?

I am trying to do this, but it doesn't seem to work. Form URl https://form.jotform.com/60077597088973

I tried this and this method is actually working in the new layout. But I think you need to revise the option, try to remove the number and symbols. Change it to a simple text option. I'm trying to do this within a clone version of your form, but it's crashing up my browser. I can't edit the condition because of this.

It was the commas in the option that were messing it up.  I think the commas must signal different options in some way.

Thanks for your input.
