If you are interested in adding more than one embed to your external website we have discovered a work around from some BLAB fans at TotallyCodable.
-Select (or add new) a Product or Service you would like to embed
-Go to 'Other Settings' Tab
Click on "Embeds" to create a new embed or find one that you have already created. Once created, copy the code to your clipboard
-You can now enter your Script code at the link below to convert it to a URL to use on any Wix site via an iFrame element. As soon as you hit the convert button it will copy your new URL to your clipboard so you can paste it in your iFrame.
