Hi Shelia,
Sweet rice flour is from a short grain  Chinese rice.  It is sometimes 
called glutinous rice flour or sticky rice flour.  I doubt that you would 
just happen to pick up that kind at your local store.  I purchase my sweet 
rice flour at a Chinese grocery.  More likely you would find what I have 
seen labeled as " rice flour".  The sweet rice flour is always labeled as such.
Hope that helped,
     Ginger
