I am trying to use update my products to use order forms which include sliders, but I cannot seem to figure out how I get the desired output.   For example I have disk space that goes from 50gb to 750gb in increments of 50GB. I have done this by creating the following configurable option:-     However this is not meaningful to end user as a slider as it just shows 1-15, whereas I obviously want it to show the amount of space 50-750   what is the best way to do this ?
