Therefore, these values are treated as invalid input.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;So i&amp;nbsp;prepopulated the field with a&amp;nbsp;0, but still the same error.&amp;nbsp;&amp;nbsp;I have been able to revert back to the original UDC and Form without issue.&amp;nbsp; I am able to open the old forms.&amp;nbsp; &lt;/p&gt;&lt;p&gt;Does this mean you cannot alter dataFields or am I doing something wrong?&lt;span&gt;* I&amp;#39;m using SharePoint 2010 and InfoPath 2011&amp;nbsp;browser based forms with no code. &amp;nbsp;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;&lt;/span&gt;&amp;nbsp;&lt;/p&gt;</description></item></channel></rss>
