Error message when linking to SharePoint

[Brook]

I have an IP form linked to SharePoint from a shared drive. The forms works
fine when our tech pubs department accesses the form, but when others within
the company access the form, an error message appears:

"This form cannot be filled out, either because you do not have adequate
permissions, another user has the form open, or the form is open in another
program. Do you want to open a read-only verson of this form?" The Yes/No
button appears.

After clicking "Yes", the user is able to fill out the form and send the
info successfully. However, it's creating confusion. Our IT dept. seems to be
stumped as well. Is there a way to suppress this message?

Thanks

Do the users have access to the SharePoint list that the form is calling?
Is it linked in the sense that the form is submitted to the SharePoint form
library or linked because it receives information from the SharePoint list
in the form? Also do the people filling it out have write access to the
network share. Because if they don't and you are using a submit button then
the form probably is being opened read only from the share but its being
written back to a different location.

Can you put the form on the SharePoint site as the starting point?
