Add element to Dynamic Panel State

I am trying to “drag-and-drop” an element into Dynamic Panel State and I simply can´t. I´ve been looking through this and can´t for some reason do it. Whenever I drag the box element to release it on the state I just get that red indicator, that indicator is telling me I can´t do this.
Actually I am following this tutorial.

Do you have any idea what I am doing wrong or if I have to do some configing on the Axure client?
Best regards,

I just downloaded Axure 9 and tried this again and it worked. So my solution was to just upgrade to the new version :slight_smile:
