Hi, Im trying to use the count function in a repeat group to summarise how  
many live births, still births etc a patient has had. The repeat group  
works fine (driven from the no of pregnancies the patient has had). I  
created a hidden value and put the following in the calculate box : count(  
outcome\_of\_pregnancy ['choice2']) where outcome of the pregnancy is the  
question asking what was the outcome and choice 2 is still birth. I got  
this error message in the app preview. Can anyone explain where Ive gone  
wrong? thanks very much, Nicola

Display Condition Error: Error in calculation for /data/no\_of\_stillbirths  
XPath nodeset has more than one node  
[/data/pregnancy\_details[1]/result\_of\_pregnancy[1];/data/pregnancy\_details[2]/result\_of\_pregnancy[1]];  
cannot convert multiple nodes to a raw value. Refine path expression to  
match only one node.
