Had Issue with Sequence Drag and Drop Learning Task

Hi Tom, it works! Thanks! I didn't know it was a drag thing, so I rewrote the correct answers over and over again...

Also, I think I saw there is an up and down arrow in each choice only sometimes, I believe it is for ordering the sequence, but when I clicked on the choices, it disappeared and I don't know how to make it show again. Could you please give me some directions? Thank you so much!
