Hi, I have two questions- 1) This is officially a window, it was not designed as a door however people use it to get in and out. It comes up from the floor but not enough that you have to climb out as though you were climbing out of a window. is it chayev a mezuzah? 2) the daled with a healthy tag caused by the metayegs slipping a little. Shinu tzurah or fixable?
