The query executed ok but I got the following warnings:

 Warning: #1364 Field 'addon' doesn't have a default value

Warning: #1364 Field 'markers' doesn't have a default value
I don't see how these warnings have anything to do with the query, but the warnings did appear after running the query... maybe they'll make more sense to you than they do to me.

Anyway... that did not resolve the problem.   Does everyone have this problem, or is it just me?
