Build a Conference Management App --> Create an Aura Component

I have tried to Copy/Paste using CTRL+C and CTRL+V, using the mouse copy/paste functions and also writing the code manually but all attempts fail. Are there any other ways of copying the text so I can complete this challenge ?

My issue seems to be very strange. I have created this process and when I test it, it is updating the sales price to deposit amount as said in the requirement. But when the chellenge is checked it gives me error message:
Challenge Not yet complete... here's what's wrong: 
The Fulfillment Cancellation Automation process does not appear to be working properly. Make sure that a cancelled Fulfillment updates the Adventure Package correctly.

Chose the fullfillment object
have proper conditions:


and update the adventure package


I tested it and it seems to be updating the sales price to the diposit amount correctly:


but still on checking Chellenge I get the error:


completedly stumped!!! please let me know if anybody faced the same issue. any help.
