Freeform Drag and Drop - limit number in drop target
Hope someone can help with a quick and easy solution! I've had a look at previous posts and I haven't been able to find a solution...
I have two drop targets and eight drag things. There are four correct ones for each drop target. I would like the users to only be able to put four things in each (and bounce any additional ones back if possible).
Currently it works how I'd like it, you can just put as many answers as you like in each drop target.
I've tried having a variable for each drop target to add up when you drag the items onto the drop target and then subtract when they're put back to an invisible shape in the start position - then having the submit button appear when the variables equal a certain number - but it gets a bit complicated if you move one of the drag items from one drop target straight into the other without it being returned. Also, quite happy to have the submit button there always.
Is this possible?
I have attached the slide (I realise the way the submit/next button works is probably a very long way round, in my defence, I'm working with someone else's content)
Any help would be appreciated,
