Maybe set the checkboxes to 1 if selected, and then have a default value for your text box that adds all of them? Otherwise, you&#39;ll need to put rules on all 4 checkboxes to change the value of the textbox when one of the checkboxes changes.</p>https://www.infopathdev.com:443/forums/thread/100706.aspxThu, 08 Jan 2015 05:27:46 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:100706kashy0https://www.infopathdev.com:443/forums/thread/100706.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=100706I have 4 check boxes and a text box.. and I need to do something like this if all CB are checked then, TB vale should be CB1+CB2+CB3+CB4 if any of the CB is not checked (for eg. if CB3 is not checked) then TB value should be CB1+CB2+CB4 How can I do this in infopath?
