Select By Location with Multiple Selecting Features

Question

I'm working on a watershed management project that requires ArcHydro tools. After creating the SinkDA and SinkPoly layers, I want to select all SinkPoly polygons that share a SinkDA polygon with an existing stormwater inlet. I've tried a few combinations of these three in the select by location tool but I'm not having any luck and would love to save the time of going through a couple thousand polygons. How should I set the tool to accomplish what I need? Am i using the right tool?

Thanks for your response, David. Unfortunately only about 15% of the SinkPolys intersect with storm inlets so it doesn't return the full selection I need. However, your idea inspired me to play around with the tool's setting and I found that selecting all SinkDAs that contain inlets, then selecting all SinkPolys within the selected SinkDAs is working out how I needed it to. Thanks again for your advice!

Going just off your description: select all stormwater inlets that intersect the SinkDA polygons, then select all SinkPoly polygons that intersect the previous selection. Only the inlets that hit a SinkDA will be selected first, so any SinkPoly selected next must be one that shares an inlet with a SinkDA.
