your PERC PE score calculator doesn't work; please correct
none of the blocks are clickable until you click "low probabilty for PE", and then when you do click it, and try to click others, it says "this rule does not apply," incorrectly. please correct!

This is how the rule works, it is only applicable in patients with a low probability of a PE (this is why you have to select YES first), and then the probability is only below 2% if ALL the criteria can be ruled out. As soon as you select YES to any criteria except the first, the PERC rule does no longer apply and you can no longer be sure that your patient is in the very low risk group.
If you feel that this is incorrect, please add a comment.
