How to set label based on string

I have a string assigned that needs to map to a label name. For simplicity:

string label = "numShifts";

I then want to set the label called "numShifts" on an object ("Processor1" in my example). I tried using the below command, but am getting a compiler error. Anyone know how I could do this.

model().find("Processor1").labels[label] = 2;

You need to use assert() to make sure the label exists. Also the label array gives you access to the label node so you have to use value.

string label = "numShifts";
model().find("Processor1").labels.assert(label).value = 2;

@Jacob Gillespie, that appeared to work well. Thank you so much. Should I be concerned with the following exception I seem to get when I run that script?

exception: FlexScript exception: /0 c: /testlink_instance i: /testlink_associated

Here is the full script that is loading, where I am opening a csv file, using the string tokenizer to set some string variables, and using those variables to set the labels on model objects.

fileopen("C:/Users/cxl300/Desktop/StationAttributes.csv","r"); // open the csv file


filereadline(); // read and disregard the header line


while(endoffile!=1){
	string line = filereadline(); // read the line
	
	string station = stringtoken(line,","); // grab the station
	string attribute = stringtoken(NULL,","); // grab the attribute name
	string value = stringtoken(NULL,","); // grab the attribute value
		
	model().find(station).labels.assert(attribute).value = value.toNum();
		
}


fileclose; // close the file

@Chris Ligetti It means that find() is not finding anything.
