Creating a small survey consisting of 13 questions in which there are answers A,B,C (Radio buttons)
How do you add the individually selected radio buttons to provide a total. of each. i.e how may A's, B's and C's. I have attached the lotus notes database to help explain.

Thanks.

The names of the radio buttons could be A1, A2, A3..., B1, B2, B3....

You would then iterate through the elements contained in some div (which could contain the table), and you check with what letter the name of the Radio starts

example1 taken from : http://www.javascriptkit.com/domref/elementproperties.shtml

example2 taken from : http://www.java2s.com/Code/JavaScriptReference/Javascript-Collections/childNodesExample.htm



example1:
//access some <ul> element
var mylist=document.getElementById("mylist")
for (i=0; i<mylist.childNodes.length; i++){
if (mylist.childNodes[i].nodeName=="LI")
//do something
}
 
example2:
 
<html>
<head>
<script language="JavaScript">
function function1() {
    var m = document.all.myBody.childNodes;
    alert(m.length) 
}
</script>
</head>
<body id="myBody">
<input id=myB 
       type="button" 
       value="How many child nodes have this body element?" 
       onclick="function1()">
</body>
</html>

document.getElementById("elementID").childNodes // returns all child nodes

***document.getElementById("elementID").childNodes(param1) // returns an individual *** (you can access properties of the individual, like it's name)

document.all.elementID.childNodes // IE only
document.all.elementID.childNodes(param1) // IE only


param1   Required; zero-based index

Hi,

assuming your question fields are called q1 - q13

Total As =

total := @Trim(q1:q2:q3:q4:q5:q6:q7:q8:q9:q10:q11:q12:q13);
result := @Trim(@Replace( total ; "B":"C" ; "":""));
@If(result="";0;@Count(result))

Total Bs =

total := @Trim(q1:q2:q3:q4:q5:q6:q7:q8:q9:q10:q11:q12:q13);
result := @Trim(@Replace( total ; "A":"C" ; "":""));
@If(result="";0;@Count(result))

Total Cs =

total := @Trim(q1:q2:q3:q4:q5:q6:q7:q8:q9:q10:q11:q12:q13);
result := @Trim(@Replace( total ; "A":"B" ; "":""));
@If(result="";0;@Count(result))

May other ways (just for fun, not points!):

total := @Trim(q1:q2:q3:q4:q5:q6:q7:q8:q9:q10:q11:q12:q13);
totA:= @Sum(@TextToNumber(@Replace("A":"B":"C"; "1":"0":"0")));
totB:= @Sum(@TextToNumber(@Replace("A":"B":"C"; "0":"1":"0")));
totC:= @Sum(@TextToNumber(@Replace("A":"B":"C"; "0":"0":"1")))

Or:

total := @Trim(q1:q2:q3:q4:q5:q6:q7:q8:q9:q10:q11:q12:q13);
totaln:= @Sum(@TextToNumber(@Replace("A":"B":"C"; "1":"1000":"1000000")));
totA:= @Modulo(totaln; 1000);
totB:= @Modulo(@Integer(totaln/1000); 1000);
totB:= @Integer(totaln/1000000)
