can you rewrite this clearer? Like i didn't understand half of it..

Do you have 2 switches or 2 pic micros? Can you use paint to draw a simple draft?

How is your switch connected to the PIC?
Can you pls draw some kind of schematic diagram showing your connection?
I'm not sure how the 2 switch is connected to the PIC.

Let me try to understand you..
You want to display data onto LCD.
Lets say initially, the value is 0, so "0" is displayed on the LCD..
When u press switch1 1 time, "1" is displayed because the data is increased by 1. When you press switch1 the second time, the LCD display "2".

When you press switch2, the data will decrease by 1 so LCD will display "1". When you press switch2 again, LCD will display "0".

Is that what you are trying to do?

Ok.. Below is what you need to do.

1) Decide on what programming language you want to use. ASM, C, Basic?
2) Decide on compilers you want to use. MPASM, CCS, Hi-Tech, mikroC, PBP?
3) Learn how to read input.
4) Learn how to use IF..ELSE statements..
5) Learn how to display things onto LCD. eg display "1", "2".

I'm not sure which part you have/haven't done so what I can do is to give u a general idea of what u need to do..
