Glitch with Character WAD editing

This may sound completely stupid, but I searched and didnt find info on this,
whenever I add a sprite to my character WAD in XWE , that particular frame doesnt show up in the actual srb2 game, in it's place is the falling animation, im not sure what to do, im basing my wad over a custom one from the site, but replacing the sprites, so I need help on what I'm doing wrong.

I should seriously add this to the FAQ.

Anyway, what you have is the classic lowercase lump problem. See the link for details on the lowercase lumps. http://wiki.srb2.org/wiki/Character_WAD#Lowercase_lump_names. If you want to know how you change the lumps to lowercase, then look at these two links on how to do that in both XWE and in SLumpED.

XWE: http://wiki.srb2.org/wiki/XWE_Tutorial#Lowercase_lumps_and_other_menu_options

SLumpEd: http://wiki.srb2.org/wiki/SLumpEd_Tutorial#Setting_Up_SLumpEd

SLumpEd has a bug where it loads in lowercase, even if you set it up correctly. It will save it in lowercase if you remember to do that as your last step.

Yeah, that worked perfectly, thank you very much
