catalog item variable to display quantity of "in stock" assets where the model category is "computer

[Taza]

Hi all,

I need some help to achieve the following in a catalog item:

When a user selects a stockroom from a variable, I would like it to then calculate and display in another field the total quantity of "in stock" assets where the model category is "computer". 

I've been browsing the community but cannot find a definitive answer to this.

Please help.

Hi,

write onChange client script of selection stockroom variable

Client Script:
    var ga = new GlideAjax('CalAssetQuant');
    ga.addParam('sysparm_name', 'getQuant');
    ga.addParam('sysparm_stockroom', newValue); 
    ga.getXMLAnswer(function(response) {
        g_form.setValue('ENTER ANOTHER VARIABLE NAME', response);
    });

script include :

    getQuant: function() {
        var stockroom = this.getParameter('sysparm_stockroom');
        var total = 0;
        var gr = new GlideRecord('alm_asset');
gr.addEncodedQuery('model_category.name=Computer^install_status=6^stockroom='+stockroom); // 6 is in stock state 
        gr.query();
        while (gr.next()) {
            total += parseInt(gr.quantity); 
        }
        return total.toString(); 
    },

Hi Mani,

Thanks, I've given it a go but it doesn't work. I've attached some screenshots.
