Ailen, since in a Raiser's Edge checkbox field a "Yes" means "check the box" and a "No" means "don't check the box" (which is the default) you simply do not need to specify the "No" value in the dictionary, just the "Yes". Try this - highlight the "No" value on the left and hit the delete key on your keyboard to remove it from the dictionary. You just need the "Yes" on the left, with the "-BLANK-" on the right (regular expressions turned off). The issue you are seeing is b/c that awesome expression of "^.+$" just doesn't play nice with other entries sometimes, and you may be able to just avoid using it to get the intended result. The blank address line should result in a check in the desired box, and an actual address should result in the box NOT being checked (the RE default). The only problem I predict is that since you are copying the address lines to determine the checkbox result, the actual addresses coming in as a "No" may confuse RE. In that case, just use this dictionary to first process the people without a valid address and let the exceptions catch the others. In a second pass, process those exceptions but switch the dictionary off and import the leftovers. Give that a try and let us know if that works for you.
