Creating and Using Merge Variables on Your Forms Follow
Merge Fields fields can gather information from other form fields and ezMerge fields into one place for you to format as you wish. The Merge Field can be located on the left under the standard fields section of your order form. Simply drag and drop this field to add it to your form.
Once you drag the Merge field out onto your form and give it a name, you will see a button called Variables. When you click on a field it will fill in on the Merge Field. You can also type text to add formatting as well, for example: "Quantity of {udf_Quantity}" will allow for the description of "Quantity of" to appear before the Quantity.
The Merge field is an excellent key for customizing your cart name, descriptions, and a powerful tool when using MIS systems for notes. Once done just Map this field to wherever you would like, for instance, the "Cart Item Name" or "Job Description Field"
