As Phil suggested, you could have done that easily with DELETE statement with WHERE Clause specifications.
About the Single and Double quotes: Both can be used. But Single quotes fit in better than double quotes around string values(non numeric, for which you don't have to use quotes around), becoz DOUBLE quotes in VBA/VBScript/
VB lang is used to wrap the Contants/strings, so within that if you would like to use quotes around string values to contruct sql statement as in your case, you got to use single quotes as specified in my previous post, ot you could use double DOUBLE quotes "" to nullify/negate the special meaning of the preceeding one.
Hope that explains.
Cheers!
