#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.
