Hi all! I’m trying to code my multistate box for the read more / read less function but there’s an error. I followed the guide from Velo on how to code but it’s not working. I would be grateful for any help! 
Hi Mily,
If the changeState doesn’t exist’s are you sure you are using a multistate box?
Also, try making an onClick event by going to the property menu from an element (right from the code when the element is selected) and where it says onClick() click it, give it a name and press enter, an onClick event for the element will be added to the code page.
Try to add the changeState in that code block and remove the onClick in the onReady function
Kind regards,
Kristof.
