I am not sure if I have understood your question correctly.
Do you mean to say that the form you have embedded in your facebook page does not work but the same form on other facebook pages works fine?
Please share your facebook page URL where your form is not working and we will take a look. I believe you must have already referred the following guide on how to embed your form in facebook: http://www.jotform.com/help/22-Adding-Form-to-Facebook-Pages
Do get back to us with your facebook page URL and we will take a look.
