error with rectangles

[JHB]

Hi,
I trying to develope some small games using the LovePotion port. Wich actualle works fine. And a guy made a cool file for testing my work on a pc without the need of an actual emulator, Wich is pretty cool. Sadly everytime i use the, and using rectangles i get an error. And i'am still not very good in coding/using love especially if its unfamiliar code.
maybe some of you guys could help me with that. I Link the file/code below.

Thanks so far.

It would help if you specify the error you get. There is nothing obviously wrong with the code.

Also, using assert that way will result in poor performance - all arguments are evaluated before the assert function is called. You will be generating new strings every time, which is slow. If it's a simple constant string though, it's ok.

Okay thats weird, just try'd it out without any changes to get that error again, and everythink work as fine as it should be ...
I'll just go on with that, i am pretty sure it doesnt last long, and i will be right here again witz "that error", i remeber it was somthing about "old rectangles".

well yeah, you are calling 'love.graphics.rectangle' with nil (no value) as the value for x. the error would be the same if you didn't use the DS code you posted (except it would read "Bad argument #2 to 'love.graphics.rectangle'")
