Zoho's Editor keeps deleting my variable??

So I have this app that was just starting to run smoothly but I've encountered the following problem.  I'll save the script but when I got to access the application there's an error that one of the values is null, and sure enough when I return to the code my variable preceding a round function keeps being deleted no matter what I change it too...anyways would really like whatever is causing it to be fixed so I can continue developing...thanks...here are some pics...
