I see what you're up to.
I modified your capx and corrected your initial event sheet.
I also added another event sheet, called "Improved" which includes a function. Functions make your life way easier and this event sheet is also more compact than your initial one. I added several comments, I hope I can help you. :)
(Switch between the Event Sheets by clicking your Layout and then choosing the Event Sheet on the left)
If you have questions, don't hesitate to ask.
Btw, you can add as many instances of Sprite2 and change their values to whatever you prefer, my improved version will still work. ;)
(I changed the movement, you now control the Blue Sprite via Drag & Drop)
