It is not possible to say where you went astray.
A wild guess would be that you ADDED the code instead of REPLACING the code.

I hope to scan for the 9. I tried substituting the lines of code and got the error that addlabel was not allowed in this context so I hashtagged out the addlabel (I have no idea what i am doing just tried something) and now i have the one plot expected error.

@MerryDay would you mind referencing which version of code I should use for the scan (which post) bc ppl are asking for adjustments to arrows and bubbles and I have no interest in that just want to scan for the 9.

thank you and I am sorry I couldnt substitute the code successfully.

Your error is only possible if you attempted to stuff code into the scan hacker.
Please don't!
Please follow the directions in the scan tutorial:

2. how to copy & paste: https://usethinkscript.com/threads/how-to-import-existing-thinkscript-code-on-thinkorswim.10/


To create a scan:

replace these lines of code:
def TDUp = TD - td_vw;
def TDDn = TS - ts_vw;
Click to expand...
with these:
plot TDUp = TD - td_vw;

Tom Demark Sequential 9 (TDS 9) is a technical indicator that helps identify a possible trend change. Specifically, if 9 consecutive candles close higher than the previous four, a reversal or correction in a stock's trend is possible.

When I copy this script to TOS, the 7,8,9 display fine, but a yellow label containing "prev n cond 1" displays at the top-left of my chart. I removed all other indicators to ensure there is not a conflict and it displays on all timeframes with all stocks. How can I resolve the yellow label?
 
@MarkTrades You can eliminate the yellow label by remarking the line of code below with a leading #:

Change
Ruby: 
addlabel(1, "prev n cond " +  prev_n_cond, color.yellow);

To
Ruby: 
# addlabel(1, "prev n cond " +  prev_n_cond, color.yellow);
