Iris,
as I said, the posted macro works for me. The text file is written and
it contains the data.
Did you wait until the macro finishes?
Please try again with:
/////////////////////////////
waitForUser("set the threshold and press OK, or cancel to exit macro");
getThreshold( lower, upper );
txt_file = File.open( "Thresholds.txt" );
print( txt_file, "Minimum threshold: " + lower + "\n" );
print( txt_file, "Maximum threshold: " + upper );
File.close( txt_file );
exit();
/////////////////////////////
Best
Herbie
