Hello @Ammad Satti,

I indeed had to add the "script" part in the "Order Guide" form.

I then added the following script:

// Get the value of my variable reference type.
var value1 = g_request.getParameter('IO:13a97e561b4fcd184c16a938bd4bcb91');
// Add the catalog item filled on the variable reference type in the options.
guide.add(value1);

But unfortunately it doesn't work.

As a reminder, I have a reference type field linked to the "sc_cat_item" table which is filled in and which must then appear in the next step as an Item to fill in.

Thanks !
