I am looking to remove rows where there are missing data points (ie row 94 below); have done previous searches on this issue and tried the fix below:
dtsplit << Select Where(Is missing(Pr) | Is missing(:weight 1) | is missing(:Strength)) << Delete Rows;

I get the following error:

This is the actual script:
dt=
Open Database(
"DSN=Excel Files;DBQ=P:\INKJETS\MDU\Chris\JMP TRIAL.xlsx;DefaultDir=P:\INKJETS\MDU\Chris;DriverId=1046;MaxBufferSize=2048;PageTimeout=5;",
"SELECT * FROM `Sheet1$`",
"Sheet1$"
);
dtsplit << Select Where(Is missing(:Product) | Is missing(:weight 1) | is missing(:strength)) << Delete Rows;
Any help would be greatly appreciated, thanks in advance.
