digital input row 3

[paultheflyer]

Hi, I have been having difficulty reading input from the third row. Rows 1 and 2 are fine. The code snippet is as follows:

void MuxInput::updateInputs() {
setMode(1,DIGITAL_IN_PULLUP);
setMode(2,DIGITAL_IN_PULLUP);
setMode(3,DIGITAL_IN_PULLUP);

for (int i = 0; i < 16; i++) {
inputs1[i] = digitalReadMS(1, i);
inputs2[i] = digitalReadMS(2, i);
inputs3[i] = digitalReadMS(3, i);
}

Serial.print(inputs3[0]);
}

inputs1 and inputs2 read fine, inputs3 however does not. Any ideas?

As a follow up: I uploaded the example code for digital input with the same result: row three does not work. I first tried with a Duemilanove then with an Uno.
