Form Changes Not Saved

[JoJo]

Has anyone experienced this? I created a new form and saved it in VBE. The next day I opened the form and continued to design the form. Saving frequently. When I ran the form, the changes are not there. Only the original form created was visible. I can make changes but they're not there when I run it even though I save the form before running it.

Any idea why this is happening?
