Scratch

as soon as I tried to view it  after it loaded the screen turned white.  then I pulled the project up on the scratch project maker and it worked just fine. then I re posted it hoping it would work then but same thing I didn't program it to turn white because after the second try I looked at it again worked just fine. again when I tried it again didn't work online. and I checked all my other projects they worked just fine. but i am using flash so that may be it.  please tell me what to do
