Your svg doesn’t appear to have uploaded. Upload is 7th icon from the left in the reply menu. As well you need to either edit the svg with a text editor or run the svg throug FritzingCheckPart.py to remove the px values that Inkscape or other svg editors add for CSS compliance (which Fritzing complains about usually by setting the font size to 0. This tutorial may also help (it has details on using FritzingCheckPart.py as well.)
edit:
A better idea is to upload the .fzpz file of your part as that has both the .fzp file and all the svgs in a single file and is much easier to correct. I also believe that it is one file per reply so multiple replies will let you upload multiple files. (one at a time still though!)
