A problem with multiple characters WAD

I'm actually made a WAD with multiple characters like SonicTeam.wad.
So when i start the game and add the wad.... The game ended and an error message appears: R_AddSingleSpriteDef No patches found for DASHA1 frame \.
So i tried something to try resolve the problem but... It always doesn't work. Please help me.

(So well my wad is has RainbowDash.wad with a super forum and a SMS with some 1.09.4 sprites and some GFX i founded in anothers WAD. The wad will not published here for avoid infraction dues to "use other works")

"No patches found for DASHA1 frame \"

Do you have the \ frame on your wad? (Should be named DASH\1, I think). This frame should be the hurt frame.

Since when were you able to put multiple characters in one wad?

Since never, AFAIK.

Actually it's not a fake. Here's an example wad.

The only problem is I just copy and paste the WAD's sprites so I not forgot the \ frame.
Well, I'm not on my personnal computeur and I can't verify the sprites today. But I probably can verify sprites Saturday and Sunday...
EDIT: I foud the problem. I don't know why but when I copy and paste the sprites, the \ frame becaume a _ frame, so I've now got a combo of RainbowDash and SMS with SONIC CD GFX.
