Share UNO with an LCD and a Logger shield

[shlomo]

looking at the logger schematic at http://www.ladyada.net/make/logshield/design.html I still have the whole JP4 8bit port available to drive a standard LCD which only requires 6 ports to operate.
When I plug the data logger on top of the UNO, connect the LCD 6 pins to the logger UNO 1 to 3 and 5 to 7 digital port extensions, and I load a well working LCD sketch I don't get it to run.
What am I doing wrong?

Did you modify the sketch to reflect the pins you are using?
Does your sketch use serial I/O? Serial uses pins 0 & 1.

Yes I modified the LCD sketch hopefully in the right way, and it works just fine by itself.
Does the Data logger use any of the first 8 dig out?
Anyway this is the beginning of sketch i am using:

LiquidCrystal Library - Hello World

20x4 LCD display. The LiquidCrystal
library works with all LCD displays that are compatible with the
Hitachi HD44780 driver.
used the Adafruit TC2004A-01


This sketch prints "Hello World!" to the LCD
and shows the time.

The circuit:
* LCD RS pin 4 to digital pin 7
* LCD Enable pin 6 to digital pin 6
* LCD D4 pin 11 to digital pin 5
* LCD D5 pin 12 to digital pin 3
* LCD D6 pin 13 to digital pin 2
* LCD D7 pin 14 to digital pin 1
* LCD R/W pin to ground
* 100 resistor to pin 15
* pot cursor to pin 3
* pin 1 to gnd
* pin 2 to +5
* pin 16 to gnd

// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(7, 6, 5, 3, 2, 1);

void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(20, 4);
// Print a message to the LCD.
lcd.print("hello, world!");

Post photos of the front & back of the board and a photo showing all your connections.

How did you know? Taking the pictures worked, it now works. Moving contacts in and out for the nth time made the difference, I wish I know which one was.
Thanks for the prompt assistance, s.-
