Use the g_service_catalog.parent object to interact with the parent form from within a MVRS script
//These methods can be used onLoad, onChange, or onSubmit in a script that Applies to the MRVS

//Retrieve a variable value from the parent form
//Retrieve a variable value from the parent form - works in native UI as well as Service Portal, etc.
g_service_catalog.parent.getValue('variable_name');

//Set a variable value on the parent form
g_service_catalog.parent.setValue('variable_name');
//With this approach, you can set a variable value on the parent form - use similar code for other g_form methods like clearValue
//Service Portal method requires an additional Catalog Client Script onLoad that Applies to the Catalog Item
if (this) { //Service Portal method
this.cat_g_form.clearValue('variable_name');
} else { //native UI method
parent.g_form.clearValue('variable_name');

Use this code snippet to interact with the parent form (i.e the main catalogue item) from within a catalog client script on a Multi-row variable set.
Use this code snippet to interact with the parent form (i.e the main Cataloge Item) from within a Catalog Client Script that applies to a multi-row variable set.

The g_service_catalog object allows for accessing the "parent" GlideForm (g_form) object and its related functions
The g_service_catalog object allows for accessing the "parent" GlideForm (g_form) object for getValue only (for now?)
To affect a variable in the main catalogue item using setValue, clearValue, etc. parent.g_form... is available in the native UI, and this.cat_g_form... can be used for Service Portal, etc if an additional Catalog Client Script is used, this one onLoad that Applies to the Catalog Item (not the MRVS).
