Hello Im very new to IP and MOSS but have been tasked to create a user input form that populates data into MOSS. I have created a form and a MOSS form library. I use a 'Submit' button and have my data connection defined to the orm library URL. The form opens in a browser window when I select 'New' from the form library and when I select 'submit' the message tells me it was submitted successfully, but no data is present in the form library. There are similar threads on this site (ie http://www.infopathdev.com/forums/p/19701/68375.aspx#68375) but this cites a solution specific to the member experiencing the problem (that is, I don't understand the offered solution). Can anybody please help?

One thing I find I still do after almost a decade of building IP forms, is the URL for my submit is incorrect, verify it is valid. sometimes the simplest things can hang us up.

Thanks Larry I have double checked the submit url ( and ensured the "/forms/allitems.aspx" is removed) but still no joy. Ian
