InfoPath Dev

Hello! I'm using Infopath 2007 and I have the big problem. I created the form with some fields (data connections), which I woul like to see and change in the table. After this I publish this template in the libary of formes in Sharepoint  2007.

 I  filled in this form and saved it. Next I tryed to change the data (form my fields of form) in the table. But they are READ ONLY!!!!! I'm a local administrator and this view is not read only. This libary is using by myself ONLY.

 Thank you in advance!!!!!!

If you go to fill out a new form, the fields aren't read only? But if you open a completed form (.xml) file, the filled out fields are read only? You don't have any conditional formatting or other logic on the fields that may have caused this? What happens if you fill out the form and save to a different location (not the SharePoint library)?

Thank you for your answer! I have already founded the checkbox in the form of  publishing "make this field available for changes in the table of data")))))))
