InfoPath Dev

hi,

i have a question. i have created a form with 2 dropdown lists and 2 field. when the user choose a value in the dropdown list it auto fill the coresponding value in the field.

now i have notice when i'm busy creating the form and testing, when i preview the form i get this error:

Infopath can not open the selected form

and what i have noticed the dropdown list is not attached any more to the table i have set.

can someone tell me what the reason is that the field keep losing the attached field

Is the error message accompanied by any additional information? (sometimes you'll have to click Show Details)

There could be a corrupt file in the source. Try doing File > Save As Source, and save to a local folder. Then Design manifest.xsf and Preview. is the error message the same?
