Dumping a dll with ollydump

Hi,

I'm trying to dump a packed DLL using ollydump. I wrote a simple program that just loads the DLL, and I've traced to the original entrypoint and am ready to dump, but I don't know how to figure out what addresses I should put in "Base of Code" and "Base of Data". Do I also need to change something in the section table?

Please help me out...
