I signed a Confidentiality Agreement when I started my employment at company that I just left.

The thing is, I just noticed I signed under the "Employer" and not the "Employee" area. Then I see that they changed the form by hand writing an R after Employee and crossing out the R where I signed and added an E.

Does this make it null and void? Shouldnt they have told me I signed in the wrong spot and ask me to fill it out again???

I am hoping this voids the agreement.

Please help asap!
