Mathilda,
I am using Wix site builder. I believe it was working at one point but it is not consistent. I am using an image on Wix as a link, so when the user clicks on the image an http request is generated. I just appended caspio specific parameters to the end per the instructions to call the Caspio web form. Is there any other way to get around the iFrame issue as a second option? But I would like to first make this option work. It should work as a Query String as Caspio describes.
Thanks.
