Signature Drink Fountain

Posts: 11
Hi guys. I am a designer that loves to think to be an engineer and I have fallen a bit stuck to a few code issues. I've never taken any programing classes and the little things I know in programing were from an architectural class that I took in college that involved using basic stamps and we learned very basic commands. Much of my tutoring has come from reading some of the great posts on this forums. Background aside here is a bit of the project.
My fiance and I are gearing up for our wedding and in the process we come up with a concept Signature drink fountain bar for our guest. The signature drink will be mixed and then added to the two cylinders which will be choreographed by 28 nozzles misting C02 into the signature drinks we will be adding. The following is a concept sketch:
Frame/chassis:
Relays/Valves/Nozzles:
Now I have made a short video where the two BS2's are programmed individually (They are NOT talking/listening to each other) and simply just have been timed to look like they are actually choreographing together. I made this video so you guys can see what I want my vision to be.

The vision is that I would like the two basic stamps to work in harmony "talking/listening" to each other to master a choreography together. I want to write "sub-routines" that can be used to make an entire show but at the moment I have come across my first road-block.
Rooadblock:
I cannot get the second stamp to stop and "listen" and wait for the signal from the first stamp (I have not connected any wires between the two stamps yet and I just want to get my codes right first) and it jumps and performs the "chase" sequence of the code. It's ignoring the Start: IF...THEN command and jumping to the performing the next command which is the "chase". What is wrong with my code?
Second question is in regards to the wiring. On the first stamp my output is PINOUT #15 and in the second stamp PinIN is #14. Do I just link them with one wire this way? Do I need a resistor on the second stamp on pinin #14?
Hope you guys can help as the wedding is nearing by and I know programing is probably going to take longer than what it took to build this thing.
Thanks and lost/STUCK in Los Angeles,

Do Until IN14=1
Gosub Chase
Loop
The program will wait at that point until the first stamp sends it a signal on IN14.
You'll have two connections between the stamps: the pin to pin connection plus a connection between ground (0 volts) on the two stamps.
More detail in the helpfile of the programming software.
Off topic, sounds like an AWFUL lot of work for a wedding!

start: 'awaiting signal from first stamp
IF (IN14 = 1) THEN
GOSUB Chase
IF (IN14=0) THEN
Gosub start
ENDIF
ENDIF
This will only go to Chase when stamp 1 sends the signal
Of course nothing will happen until IN14=1, is that what you want
or do you want it doing something else until stamp 1 sends the signal?

----Resistor?· Nah. That is.....as long as you keep p14 an input.
----The gosub is not needed .... cause you don't· "return"·instead, you use a goto start.
>>If it was working right, the gosub will cause a crash after·too many gosubs w/o returns·anyway...<<
And (bookmark A)·as·your code is written,·that 'goto' isn't needed as main drops into start anyway.
(unless you didn't post a part of code that was·in-between.)
Speaking of dropping down.....(bookmark
After you checked for p14 high... you let it "drop down" the code into 'chase' anyway.
(That's why it never waited.)
Simplest fix is to hop back up to Start if p14 is low.
So....
start: 'awaiting signal from first stamp
IF (IN14 = 0) THEN
···· Goto start
ENDIF
goto chase 'optional··the way you've displayed code..it falls into chase.
That's all you'll need!·
when pin14 goes high it will stop running back to start and fall into chase.
After chase runs.....back to the loop
As a personal preference here.......I· prefer
start: 'awaiting signal from first stamp
on in14 goto start,chase················ ·'zero--goto start· one---goto chase
goto chase ' don't need it anymore!
with·the "on ... goto"· you get a bit more control (over accidental errors)!!
since you fill in the blanks it's more likely you'd catch a "mis-send" even at·
AND...it's a one-liner!
That said....sweet ride...uh...project!!
(It's always that one little·thing that snags the rest!)

the "if then" uses 16 blocks of Eeprom
while, the on goto uses 8 blocks (well it indicates 10 but 2 of those are "00" so......)

it would also be much simpler if you used TTL to have your stamps communicate
