Default wiring question -- switch to GFCI?

I'm trying to wire up a new circuit for a diswasher and garbage
disposal. I know that it would be ideal to have dishwasher and disposal
on separate circuits, but I'm out of circuits. I will eventually put in
a sub board for the garage, but for now, this will have to do.

The circuit is fine, everything tests out well, the neon tester looks
good. Here's the chain I've built:

1. Circuit board - 2-wire - single pole switch (for disposal)

2. Same single pole switch - 3-wire - GFCI outlet to go under the
sink for the disposal

3. Same GFCI outlet - 2-wire - the dishwasher hookup.

I've got the 3-wire in the middle, to feed the red as the switched
"hot" to the GFCI receptacle. The black is also hooked up as the
constant for the switch, which runs straight through to the dishwasher
hookup.

The power hits the switch fine, the switch "switches" fine, but
somewhere past the switch it dies, the first GFCI outlet never powers
up. If I run the tester from ground - red wire, it works. If I run the
tester from ground - white wire, the yellow "tripped" light comes on.

The tester shows that at the dishwasher hookup, past the GFCI outlet,
ground - black wire is hot, ground - white wire is not.

I've got a similar setup elsewhere, going GFCI - switch - light
fixture - GFCI outlet, and it all works peachy.

Is there something I'm missing? Does hooking up a switch to a GFCI
outlet require some special wiring or something that I'm missing? It's
definitely connected to the ground, and when I test the wires going
into the first GFCI outlet, they all work fine (once the switch is on).

Do I maybe not need the GFCI for the disposal? It seemed like it's
mighty close to water, which I believe is the main criteria.

Any advice? I'm stumped.


Thanks,
John
