How to concatenate fields without spaces

I would like to generate a unique ID based on a couple of different boxes. So for example, my coupon code would be firstnamelastname2017 with no spaces between any of them. When I calculate the field's value, it creates a space in between the first name and last name. 

The Full Name field value has a space between the first and last name. As a workaround, you might consider using separate Text box fields from Quick Elements to create First and Last name fields, then use those fields in calculations.
