    I am using CRM2011 trying to hide a Lookup field (SubPracticeArea) until another Lookup field(PrimaryPracticeArea) is populated. Below is my script

    function DisableSubPracticeAreaLookup() {
       var PrimaryPracticeArea = Xrm.Page.data.entity.attributes.get("cpdc_primarypracticearea").getValue();
        if (PrimaryPracticeArea == false) {
           Xrm.Page.ui.controls.get("cpdc_subpracticearea").setVisible(false);
        }
        else {
           Xrm.Page.ui.controls.get("cpdc_subpracticearea").setVisible(true);
        }
    }

    I keep getting an error that 'Onload' is undefined.....how can I fix this?

    you usually get that error when there is script errors. Is this the only script?. Check if you have forgotten a closing }.

    also it may be more appropriate to check for null.

    PrimaryPracticeArea == false

    PrimaryPracticeArea == null

    Jithesh is correct, check for null rather than false. I think there are some more scripts running on the page that could be causing error.

    Hi,

    I think you need to check for null rather than false.

    Hi,

    which function name is set in field/form event?

    Sounds like the function name "Onload" is set in event properties but does not exists in your jscript code.

    Change your code like below

    if(Xrm.Page.data.entity.attributes.get("cpdc_primarypracticearea")!=null && Xrm.Page.data.entity.attributes.get("cpdc_primarypracticearea").getValue()==null)

     {
           Xrm.Page.ui.controls.get("cpdc_subpracticearea").setVisible(false);
        }
        else {
           Xrm.Page.ui.controls.get("cpdc_subpracticearea").setVisible(true);
        }
    }
