Populate Order Guide Variables from URL

[litchick10]

I want to create a URL that opens an Order Guide and populates 2 values.  We are on the Now Experience and I can't seem to get this to work in any way.  

Here's what I've tried:

Option 1

[our instance]/now/nav/ui/classic/params/target/com.glideapp.servicecatalog_cat_item_guide_view.do?sysparm_guide=D7577104bc31fa250d60479bdc00131ff%26sysparm_catalog_view&sysparm_rt=Update&sysparm_sqt=89e358f8c3776e10d60479bdc0013134

Doesn't open order guide, screen says not authorized

Option 2
[our instance]/now/nav/ui/classic/params/target/com.glideapp.servicecatalog_cat_item_guide_view.do?sysparm_initial=true&sysparm_guide=7577104bc31fa250d60479bdc00131ff&sysparm_catalog_view=catalog_default&sysparm_view=catalog_default&sysparm_rt=Update&sysparm_sqt=89e358f8c3776e10d60479bdc0013134

This opens a without setting variables and converts to: 

[ourinstance]/now/nav/ui/classic/params/target/com.glideapp.servicecatalog_cat_item_guide_view.do%3Fsysparm_initial%3Dtrue%26sysparm_guide%3D7577104bc31fa250d60479bdc00131ff%26sysparm_catalog_view%3Dcatalog_default%26sysparm_view%3Dcatalog_default%26sysparm_rt%3DUpdate%26sysparm_sq%3D89e358f8c3776e10d60479bdc0013134?sysparm_initial=true&sysparm_guide=7577104bc31fa250d60479bdc00131ff&sysparm_catalog_view=catalog_default&sysparm_view=catalog_default&sysparm_rt=Update&sysparm_sqt=89e358f8c3776e10d60479bdc0013134

Option 3:

[our instance]/now/nav/ui/classic/params/target/com.glideapp.servicecatalog_cat_item_guide_view.do%3Fsysparm_initial%3Dtrue%26sysparm_guide%3D7577104bc31fa250d60479bdc00131ff%26sysparm_catalog_view%3Dcatalog_default%26sysparm_view%3Dcatalog_default%3Fsysparm_rt%3DUpdate?sysparm_rt=Update&sysparm_sqt=89e358f8c3776e10d60479bdc0013134

Loads, doesn't convert but doesn't populate variables

Using the OnLoad Script:

function onLoad() {
    var type = getParameterValue('sysparm_rt');
    var sqID = getParameterValue('sysparm_sqt');
    if (requestType) {
        g_form.setValue('request_type', type);
    }
    if (sqID) {
        g_form.setValue('request_type', sqID);
    }
}

function getParameterValue(name) {
    var url = document.URL.parseQuery();
    if (url[name]) {
        return decodeURI(url[name]);
    } else {
        return;
    }
}

@litchick10 Is the isolate script field on your client script false?

That should be marked false.

I got it working by unchecking "isolate" on the client script

Great!! That was the catch here.
