If the value of the textbox is NaN, then it is not blank. You might have to tweak your rules. If you want, please post a screenshot of the rule(s) using the Options tab.<br /></p>https://www.infopathdev.com:443/forums/thread/64717.aspxTue, 01 Mar 2011 22:01:27 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:64717mgarant0https://www.infopathdev.com:443/forums/thread/64717.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=142&PostID=64717<p>Hello there,</p> <p>&nbsp;I have a form in wich I filter some data from a sharepoint list to populate a textbox. But it happens most of the time that&nbsp;the filter returns nothing, and when it happens, there is this big ugly &quot;NaN&quot; appearing in the textbox.. I would like to put 0 instead of &quot;NaN&quot; so I can use this value to do some calculations... I&#39;ve tried setting some rules like if textbox is blank, then put 0... and stuff like that, but it didn&#39;t work...</p> <p>&nbsp;Anyone knows how I could do this?</p> <p>&nbsp;Thanks a lot!</p> <p>&nbsp;</p>
