E2 Command Screen issues

[/2usty]

I am trying to learn how to use the Command Screen in Expression 2 / Wirelink, but I am having some trouble highlighting and then selecting an option.

I will post my code below:

@name Second Console Screen Test
@inputs CS:wirelink Up Down Power Select
@outputs  
@persist O1 O2
@trigger 

#---------------------------------------------#

if(Power==1 | ~Power==1)
{
    O1 = 1
    O2 = 0
    
CS:writeCell(2041,1)
CS:writeString("Welcome to rustyOS,",0,0)
CS:writeString("please select an option:",4,1)
CS:writeString("Option 1",0,3,900,90)
CS:writeString("Option 2",0,4)
}
if(Power==0 | ~Power==0)
{
CS:writeCell(2041, 1)
}

#---------------------------------------------#

if(Down | ~Down)
{
    O1 = 0
    O2 = 1
    
CS:writeCell(2041,1)
CS:writeString("Welcome to rustyOS,",0,0)
CS:writeString("please select an option:",4,1)
CS:writeString("Option 1",0,3)
CS:writeString("Option 2",0,4,900,90)    
}

if(O1 == 1 & Up | ~Up)
{
    O1 = 1
    O2 = 0
    
CS:writeCell(2041,1)
CS:writeString("Welcome to rustyOS,",0,0)
CS:writeString("please select an option:",4,1)
CS:writeString("Option 1",0,3,900,90)
CS:writeString("Option 2",0,4)
}

#---------------------------------------------#

if((O1==1) & (Select | ~Select))
{
CS:writeCell(2041,1)
CS:writeString("You have selected:",0,0)
CS:writeString("Option 1",0,1,900)    
}
if((O2==1) & (Select | ~Select))
{
CS:writeCell(2041,1)
CS:writeString("You have selected:",0,0)
CS:writeString("Option 2",0,1,900)    
}

The problem in this code is that when Option 2 is highlighted, and O2's value is equal to 1, when I hit the button hooked to select it takes me the String "You have selected: Option 1", I cannot see why.

I am also using method I developed myself to highlight each option (which probably isn't too orthodox) and I was wondering if there is an easier way around it?

In a summary, what I want this code to do, is highlight an option when a button is pressed (by pressing the down button it goes down and up goes up) and when a option is highlighted, when you press the button hooked to select, it will display a message which indicates which option you have selected.

Please, please, please could somebody help me with this, it is really driving me insane!

Thanks in advance.
