Help! I've created some forms that work fine for me but some users are getting error messages. I submit the form to projectnet.companyname.com/siterequest/request%20site. However, when the user submits the form they get an error message which says The form cannot be submitted to the following location: projectnet.companyname.com/siterequest/request site

The site may be offline, read-only, or otherwise unavailable

 It looks like it's because I have spaces in my library name (I don't do that anymore).

Can anyone tell me why it will happen on some users' machines and not on others? Also, it's an old a heavily used library so what would happen if I renamed it? Could I even rename it?

check if this helps

Thanks for the article. I sent it to my help desk and they are going to try it on my machine. However, I have 4 forms up and running and only 1 library generates this error. Do you think this will fix it or can you think of something else I should look at?

 Appreciate your help.

 then the best thing will be to check the user permissions on the doc library.
