Hi @Aditya02 

I have tested it on my PDI and it is working as expected. Can you please share your script and the name of the list collector variable to debug it further ?

Thanks & Regards

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

        return;

    }

    var values = g_form.getValue('multiple_choice').toString().split(',');

    var listCollector = g_list.get('multiple_choice');

    var selectedOptions = g_form.getValue('multiple_choice').split(',');

    if (values.length > 2) {

        alert('Please select only 2 values '+selectedOptions);

        var index = 0;

        for (var i = 1, leng = values.length + 1; i < leng; i++) {

            listCollector.removeItem(selectedOptions[selectedOptions.length - i]);

            index++;

        }

    }

    //Type appropriate comment here, and begin script below

}

name of list collector variable is: multiple_choice

Amit Here i also want to remove some choices based on selection of another variable.

i have state variable. if state is new, i want to remove all the options from the list collector except two options, else do nothing.

Hi @Aditya02 

On which variable you have kept the On-Change catalog client script ? I just copied your script and it is working as expected on my end. It should be On-Change of list collector variable.

Also, if the state changes to new, which two options to you want to remove and from where in the list collector ( Available Values or Selected Values). As we are keeping restriction on the selected values in the list collector to 2, I assume that it will be on the selected values only. If yes, then we need to keep an On-Change Catalog Client Script on the State field so that it can control the list collector field.
