Passing array values with Dynamic Text Extension?

Hi there!

We’re trying to pass several checkboxes’ values from one page to another one in which there’s a Contact Form. In the first page the user selects several items and in the next one he asks for a budget and that’s why we need to show all the items selected.

So far, we’ve succeded when only one checkbox is selected (using the “CF7_GET key=’NAME_OF_THE_KEY'” method), but when choosing several checkboxes (in other words, when creating an array) it echoes this error

“Warning: urldecode() expects parameter 1 to be string”

Is there any way to get this array’s values with the Dynamic Text Extension? Or we will have to create a new function in the php?

Thanks for your attention,
