CRM 2011 JavaScript "Weighted Value" Any help is really appreciated.

Good day,

I've been stuck on this for days now and I can't make any progress.

I'm trying to create a OnChange event to trigger when the OptionSet is changed to calculate a new weighted value i.e.-

value * probability /100 = new read only field

value =                        Currency                     "estimatedamount"
probability=                OptionSet(25/50/75)   "leadqualitycode"
new read only field=   Currency                    "pi_weightedestvalue"

I've created a Web Resource with the following Java...however I'm further away now than I was three days ago.

function UpdateField() {

est = Xrm.Page.GetAttribute("estimatedamount").getValue();
prob = Xrm.Page.GetAttribute("leadqualitycode").getValue();

if(est.getValue() != null)


Xrm.Page.GetAttribute(pi_weightedestvalue).setValue( est * prob * 0.01)



Any help is hugely appreciated.

What happens when you try to execute this? Also how familiar you are with JavaScript and XRM Page object model?

Thank you Feridun,

You are my hero, your solution worked perfectly first time. I now get a weighted value that saves correctly and without errors.  

Kindest regards,

This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
