yeah i just tried it and it didn't work
you'll need a label with the validation condition "False()" or "0" that only shows up when your hidden calculation is the value that you want to break the form "display condition: value != 100"
this label shows you your score "number to check against" this one will show up if the calculated value "hidden calculation" is not 100. when it shows up, it won't let you submit the form. if your score is 100, it'll disappear and therefor you can submit your form
