This is a very thin (and probably trivial) usability issue but I'd like your input. The user of a webapp is editing his/her profile settings. For each setting there is a label, the actual input/checkbox and a small piece of help text giving more insight on the setting itself.
Notifications: [X] We'll notify you 5 days ahead with such and such... Days ahead for [ 5 ] notification: Controls how many days ahead you'd like to hear from us.
So, is this helpful? Or should I just play safe and change the help text of the first option to something generic like "We'll notify you with such and such..." ?
