ASM Hooplah

Hey, i'm currently buggering around with asm and registering lua functions but my asm is wrong. I could really do with a hand sorting it out.

Basically I am trying to create a function inside wow which stores a value in a predetermined area of memory.

e.g. something analogous to:

int MyVar; 
void MyFunc(int i)
{
        MyVar = i;
}

My current LUA function looks like this

                Asm.AddLine("push ebp");
                Asm.AddLine("mov ebp, esp");
                Asm.AddLine("sub esp, 0xC0");
                Asm.AddLine("push ebx");
                Asm.AddLine("push esi");
                Asm.AddLine("push edi");
                Asm.AddLine("lea edi, [ebp-0xC0]");
                Asm.AddLine("mov ecx, 0x30");
                Asm.AddLine("mov eax, 0x0CCCCCCCC");
                Asm.AddLine("rep stosd");
                Asm.AddLine("mov eax, [ebp+0x8]");
                Asm.AddLine("mov [" + pMyVar + "], eax");
                Asm.AddLine("pop edi");
                Asm.AddLine("pop esi");
                Asm.AddLine("pop ebx");
                Asm.AddLine("mov esp, ebp");
                Asm.AddLine("pop ebp");
                Asm.AddLine("retn");

Once regestered I can call the function fine.
/console MyFunc 1 //set MyVar to 1

But it's not actually storing the variable as I would like it to.
Instead it seems to be storing a new location in MyVar:
0x012A2168;

This appears to store the last thing typed into the console i.e.
"MyFunc"

Can anyone spot the error in my asm?
Thanks very much.

Nevermind, i've sorted it now.

Would you mind sharing the solution with us?

Basically ebp was pointing to the name of the console command being run (or attempted).
It was actually esi that was pointing to the input for the command.
