Arduino pins problem + lcd + ethernet + sd card

Hello i was trying to use a sketch of

Basically used to send html website messages to my arduino (freetronics mega)

The programming works fine

But i think there is :confused: a problem with the pins interfering between the lcd and the sd card
i dont know what to do?
i heard you need to cut some of the pins of but its kinda scaring me.

does anybody have an idea

Ps
Im using
freetronics lcd 16x2
freetronicsMega 2560
and a 1 gb sd card

does anybody have an idea

Yes. I have the idea that you should post your code.
I have the idea that you should post a schematic showing how things are connected.
I have the idea that you should post links to the hardware, not vague descriptions.
I have the idea that "I think there is a problem" is too vague to mean anything. Explain WHY you think there is a problem and WHAT you think the problem is.

Need more information:

  • How are the LCD etc. connected? On a Shield? External?

  • What pins are being used for what purposes?

Some LCDs like THIS: use only 2 pins.
