Dataserver problem

Ok I am really really confused....

I made a test script to read a notecard within an object as show below:

integer iNotecardIndex;
integer CardLine = 0;
key CardDataRead;
string sNotecardName;
string CardName;

default
{
    state_entry()
    {
        llSay(0, "Hello, Avatar!");
CardName = llGetInventoryName(INVENTORY_NOTECARD, 0); 
CardDataRead = llGetNotecardLine(CardName, CardLine);
    }

dataserver (key Data_id, string CardData) {
    if (Data_id == CardDataRead) {
        if (CardData !=EOF) {
            llSay(0, (string)CardLine+": "+CardData);
            ++CardLine;
            CardDataRead = llGetNotecardLine(CardName, CardLine);
}
}
}
}

This is mostly based of a script from LSL Wiki. This works perfect - YAY!

When I transplant that into my main script where it is needed it turns into this:

integer ENT = 0;
integer iNotecardIndex;
integer CardLine = 0;
key CardDataRead;
string sNotecardName;
string CardName;

// This is a basic security function that will allow two preset people to open the door only.
doorlock(string whoisit)
{
ENT = 0 ;
CardName = llGetInventoryName(INVENTORY_NOTECARD, 0); 
CardDataRead = llGetNotecardLine(CardName, CardLine);
    }

dataserver (key Data_id, string CardData) {
    if (Data_id == CardDataRead) {
        if (CardData !=EOF) {
            if ( whoisit = CardData)
            {
                ENT = 1;
           } 
                ++CardLine;
                CardDataRead = llGetNotecardLine(CardName, CardLine);   

}
}
}

And then promptly throws up a syntax error on the "dataserver" command and fails to save/work.

Can anyone see what the heck I have done wrong there? The code that reads the nodecard is an exact copy. I cannot see why SL is failing to save/run that at all.

Can anyone see what I Cannot and tell what I have done wrong?

Thanks

At the bare minimum, every script needs a default state. You will also need an event; touch_start, state_entry, listen, on_rez, etc to call the data server event.

Also, for when you get this working again, you PROBABLY meant "if ( whoisit == CardData)". Note the double equals sign for a comparison. You had a single equals sign, which is an assignment.

EDIT: Oops. Actually, I see "whoisit" isn't even in scope there, unless there are some more global variables you aren't showing.
