I extracted contours from a raster elevation file (SRTM). The contour layer does not contain elevation values. How can I use qgis to assign elevation values to the contour layer? Is there a better way to obtain contours with elevation values?

I performed the following steps to extract the contours: Raster - Extraction - Contour

Additional information: Windows operating system WGS84 projection Raster filetype: .tif Resolution: 1 arc-second

You need to make sure you check the attribute name box when converting the raster or the attributes will not be attached (as the note says).
