I've got two three-way switches and trying to control two fixtures in between and cannot quite figure out the schematic. Have 2-wire coming into the first switch, 3-wire to the first light box, 3-wire to the second box and 3-way terminating at the other switch at the end.
Suspect I've mistakingly wired the thing in series rather than in parallel and that I should have a different configuration of wires. However, all is rocked over so I'm stuck with what I've got and wonder if there is any way to make it work as is.
If there's no way to make this work, I'd be willing to drop the second switch and have the whole thing run off of one switch if that is the only way to make it work
Thanks in advance. Robert.

Yes you have them wired in series. Without adding some more cable you can not do it.
Here are some drawings that show what should have been done.

As Joe says, it's impossible given your current cabling.
Here are some of your options. If you tell us which one you prefer, we can help guide you through it: Add one more wire between the two lights. You can do this by replacing the 3-wire between the lights with a 4-wire, or with two 2-wires, or by just adding another 2-wire alongside the existing 3-wire. This is not my preferred solution, because it can make the fixture boxes crowded with wires. Run the 3-wire from to the second switch from the first fixture rather than from the second fixture. Add a 3-wire between the two switches. Or, if you really want to use just the cable you already have in place now, you can abandon the second switch and use only the first. Same as previous, but abandon the first switch and use only the second.
