I am receiving a string via blutooth and if the string is a certain word I want to change the colour of the text box.
If it is any other word i want to change the text displayed and the colour.
There is obviously something wrong with these blocks as they dont 'find' NEUTRAL
My string is received in received_data4 field which I know is working if I just display the field.
Your current 'if' will work for an identical match, that is, if the received string and the "test" string match:
NEUTRAL = NEUTRAL
Neutral = Neutral
Ensure that 'splitdata' is a List, has the correct number of indexes and your code is selecting the correct index. (Use 'Do It')
Another way is to use the Text Comparison Block - which does not require the data to be split into a List (but you can test List Items with it if required).

Thanks. I inserted the IF block into the main code and again I know I am receiving NEUTRAL but the IF doesnt seem to work??
Maybe your NEUTRAL message is immediately followed by another message without NEUTRAL, wiping away the results of the NEUTRAL message?
Add a logger procedure to capture all incoming messages.
... you only need to check the length of the List once! If it is incorrect, that is a data receive fail, end of.
Can we see your Script that formats the data from the BT device?
Script is below.....I start with casting some floats
int battv;
int tempv;
int fuelv;
String gearv ;
battv = (int)batteryVolts;
tempv = (int) oledTemp;
fuelv = (int) litres;
if ( ipArray [6] == LOW ) {
gearv = "NEUTRAL";
}
if (millis() - igUpdateTime > 500)
{
batteryRead();
watertemp();
igUpdateTime = millis();
Serial1.print (battv );
Serial1.print ("|");
Serial1.print (tempv);
Serial1.print ("|");
Serial1.print (fuelv);
Serial1.print ("|");
Serial1.print (gearv);
Serial1.println();
}
