Dear list,

I have hit a problem writing a macro. In esscence, measurements are taken of ROI from multiple images and stored in a single Results table. Some of these values then need to be altered as part of a user feedback loop. When storing the measurements, the ROI name, as retrieved by the getInfo("roi.name") command is used as an identifier.

The table I end up with looks like the following, albeit with several thousand rows:

  Label        Area              IntDen
1 0172-0039 4.78000E2 1.45210E4
2 0173-0058 6.64000E2 1.93700E4
3 0174-0056 2.06000E2 2.64430E4

If I try to select a row based on the Label value using the following:

x = "0172-0039";
y= 600;
for(i=0; i<nResults; i++) {
        rowId = getResult("Label", i);
        if(rowId==x) {
                   setResult("Area", i, y);
       
        }
}

I get no return result. I added a print function before the If to see what value of rowId was being obtained, and was given NaN. Is there a way around the non-numeric error or is there an easier way to do what I would like to? Any help or suggestions would be welcome.
