How to use file uploads, multiple options, and text fields
Example of Product Description: Mailing label size 4 x 6. Enter custom text & upload your own design.
Product Customizer Tip: To get the most of your customizations you can build multiple customizations using "If yes" statements. You can first use the multiple options customization and ask if a customer would like your product or email signup, etc. Then if they would like it you can create a text input in the next customization asking them to enter in their email. It is best if you can fit "If yes" into the Product Name section. See Picture Example below:
