Mask for field

I set too many conditions.
1) while the " Files "fields are empty, the" Checkbox " field is hidden, tab 2 is hidden.
2) the "Checkbox" field will become visible after downloading all three files.
3) tab 2 will become visible if the "Checkbox" is checked.

Now I understand that these conditions are very confused and it is better not to do so.

Thank you, I believe I understand what's happening and reopened the following ticket to see if I can fix the error at the very least as we don't want our JS fatally failing like that.
