BIGGEST PROBLEM!!!!!!!!!!!!!

Now I know how to make it into an animation. I go to gimp and click on file,
Then I click on open as layers and select all of my frames. Then I click save as and then click on a Gif file. Then i export it by saving it as an animation. Be sure to select loop forever.

But the main problem is that I did not set my 315 frames into SOLID! That might mean that I have to make my frames all over again!!!
I'll have to ask sir....
