Is it a PDF form or web form?
For PDF forms, you need to regenerate and redistribute them everytime you make a change
For web forms, changes automatically show up online. If they don't its likely you are modifying a duplicate of the form, and not the one posted.
If that's not the case can you provide more details on your workflow leading up to this issue?
The form finally upated. My internet browser was frozen and didn't update but I refreshed the page and now it's updating just fine.
