Texture Coord Problems

I''m having trouble trying to figure out what the texture coords for these verts are suppose to be. Can anyone help? for(iRows = -Height *.5f; iRows < Height * .5f; iRows +=Step) { thePlane[count].Pos.x = -Width * .5f; thePlane[count].Pos.y = 0.0f; thePlane[count].Pos.z = iRows; thePlane[count].UVCoord.x = 0; thePlane[count].UVCoord.y = 0; count++; for(iCols = -Width *.5f; iCols <= Width * .5f; iCols += Step) { thePlane[count].Pos.x = iCols; thePlane[count].Pos.y = 0.0f; thePlane[count].Pos.z = iRows; thePlane[count].UVCoord.x = iCols; thePlane[count].UVCoord.y = iRows; count++; thePlane[count].Pos.x = iCols; thePlane[count].Pos.y = 0.0f; thePlane[count].Pos.z = iRows + Step; thePlane[count].UVCoord.x = iCols; thePlane[count].UVCoord.y = iRows + Step; count++; } thePlane[count] = thePlane[count - 1]; count++;
