I've having trouble merging (dissolving?) polygons. I have 6 zip codes that I want to aggregate into one area (to make them more similar to the zips around them). I've tried using merge and dissolve, both on the original layer and on a layer of just these six zip codes, and they don't merge or dissolve. Each polygon remains intact. I think dissolve is what I really want to do - to dissolve the boundaries between the polygons so that they're all one - but if there is a better tool for this, I'd like to know. Otherwise I must be missing something...can anyone help? Thanks.

Okay, after trying to figure this out, then posting here, then going back to it, it suddenly fell into place. When using Dissolve, DON'T use the optional Dissolve Fields, and DO use the Statistics Fields.
