Form Validation Problem

What I understand from the screenshot is that you have two forms in one page and while showing errors of one form, the error displayed on both forms.

I guess you are using the function validation_errors() for showing error. I suggest you to use form_error() function to show individual field error using their name attribute.

Here is the link to documentation of this function.
