# calculation only allowed if enough items entered

Posts: 4
Hi,

I want to calculation a Score with 7 items. Each item has 6 values (0,1,2,3,4,999). 999 is for not entered.
To calculate the score, 4 ore more items must be entered.
So I made a "help" calculation, which calculates how many items are not entered:

calc_missing               func: ((Item1+Item2+Item3+Item4+Item5+Item6+Item7)/999)

worked perfectly
for score calculation I used following funktion:
score                         func: decode(calc_missing,>3,999,(100-(((((Item1+Item2+Item3+Item4+Item5+Item6+Item7)-(999*calc_missing))/(7-calc_missing))*100)/4)))

the calculation works but >3 is ingnored...I found out that decode can't handle > or <

Now my question ist, how can I handle this problem without RuleDesigner?

Hi Leonard

Alicia provided a solution to a similar problem in this post [1]. Although,
this requires that every item has a value, and probably wont cover the '4
or more items' requirement.

The alternative is to use javascript. There are some examples of this at
[2] and [3].

Best regards,
Lindsay

Hi Lindsay,

I tried to integrate the javascript, lile trialdatasolutions
but nothing happens...

here is my script (I'm using OC 3.3):

<script src="includes/jmesa/jquery.min.js">// for OC versions before 3.1.4, use jquery-1.3.2.min.js !</script>
<script lang="Javascript">
\$.noConflict();
//find out who's who

var fieldKoos-s = \$("#koos-s").parent().parent().find("input");
var fieldKoos-p = \$("#koos-p").parent().parent().find("input");
var fieldKoos-s-mis = \$("#koos-s-missing").parent().parent().find("input");
var fieldKoos-p-mis = \$("#koos-p-missing").parent().parent().find("input");
var fieldKoos-test = \$("#koos-test").parent().parent().find("input");

function calculateSympt(){

if (fieldKoos-s-mis > 3) {

var Symptom = 999;
}

if (fieldKoos-s.val() != Symptom){
fieldKoos-s.val(Symptom);
fieldKoos-s.change();
}
function calculatePain(){

if (fieldKoos-p-mis < 5) {

var Pain = fieldKoos-p;
}
else {
var Pain = "999";
}
if (fieldKoos-p.val() != Pain){
fieldKoos-p.val(Pain);
fieldKoos-p.change();
}

// fire when anything is entered
fieldKoos-p-mis.keyup(function(){
calculateSympt();
calculatePain();
});

fieldKoos-test.keyup(function(){
calculateSympt();
calculatePain();
});

});
</script>

Hi Leonard,
Maybe you could use an array to loop through the items. I tested it with <div id="I1"></div>, <div id="I2"></div>, etc  and then your code would be like below:
I hope this gives you enough info to get started.
Kind regards,
Gerben Rienk

<script src="includes/jmesa/jquery.min.js"></script>
<script>
\$.noConflict();
var fld=[];
var divName;
var numberOfMissings;
var totalScore;
for (var i=1; i<=7; i++){
divname="#I" + i;
fld[i] = \$(divname).parent().parent().find("input");
function calculateScore(){
numberOfMissings=0;
totalScore=0;
for (var i=1; i <= 7; i++){
if (fld[i].val()==999){
numberOfMissings=numberOfMissings+1;
}
else{
totalScore=totalScore+Number(fld[i].val());
};
if (numberOfMissings > 3){
totalScore=999;
}
console.log("number of missings: " + numberOfMissings);
console.log("total score: " + totalScore);

};
fld[7].keyup(function(){
calculateScore();
});
calculateScore();
})
</script>
