Verify that the check box is really using 1 and 0. Double-click the check box and look at the checked and cleared values in the Check Box Properties dialog box. See if it is using 1/0, yes/no, or true/false.
This might be the problem -- or maybe not.

Hi,
I've set up an infopath form that calls a webservice that returns a dataset.
The dataset returns 2 strings and a boolean field per record. I have a
problem with my boolean field, which is a checkbox on infopath, showing up
with the correct data. It always shows unchecked no matter if the record
has a 1 or 0 in the database. Any help or suggestions would be greatly
appreciated.
Thank you,
Kay
