ibarHour = getHour(0) Is ibarHour a number? Why does it not read it as a number?

[WantToLearn]

I have a program that will not work and I can't figure out why. In funciton main() I am reading the minute, hour, and day of the bars in a one minute chart. I can place a debugPrintln() immediately after where it reads what ibarHour is and it will give it to me. But when it comes time to read these numbers as ibarMinute, ibarHour, and ibarDay in an if statement it will not read the numbers, especially in this line:
if(ibarHour = 9 && ibarMinute = 30) {
Is ibarHour a number or something else?

The goal is to determine the slope, intercept and r2 for data between 9:30 AM and 10:30 AM EST.

Been working on this for 9 hours with no luck, can anyone help out please??? If I am not clear in explanation, please let me know.

    setShowCursorLabel(false);

function main() {
    
    var ibarHour = getHour(0);
    var ibarMinute = getMinute(0);
    var ibarDay = getDay(0);
    
    iLength = 60;
    
    if(ibarHour = 9 && ibarMinute = 30) { //This line produces an error, why??
            var isumx = 0;
            var vsumy = 0;
            var vmultxy = 0;
            var vsquaredy = 0;
            var vsquaredx = 0;
        }
    }
        
    if(ibarHour = 10 && ibarMinute <= 30) {  //calculates from 10:00 to 10:30 AM
            var isumx = isumx + 1;
            var vsumy = vsumy + close(0);
            var vmultxy =  vmultxy + (isumx * close(0));
            var vsquaredy = vsquaredy + (close(0) * close(0));
            var vsquaredx = vsquaredx + (isumx * isumx);
        }
    }
         
    if(ibarHour = 9 && ibarMinute <= 59) { //Calculates from 9:30 to 10:00 AM and adds them to the one above.
            isumx = isumx + 1;
            vsumy = vsumy + close(0);
            vmultxy =  vmultxy + (isumx * close(0));
            vsquaredy = vsquaredy + (close(0) * close(0));
            vsquaredx = vsquaredx + (isumx * isumx);
        }
    }
  // Calculates slope, intercept, and r2      
    slope = (iLength * (vmultxy - vsumy * isumx))/(iLength * (vsquaredx - isumx * isumx));
    intercept = (vsumy - slope * isumx)/iLength;
    r1 = (iLength * vmultxy - isumx * vsumy);
    r2 = ((iLength * vsquaredx - isumx * isumx) * (iLength * vsquaredy - vsumy * vsumy));
    rsquare = (r1 / r2) * (r1 / r2);
    
          
    return;

If you look at the message in the Formula Output Window it tells you the reason for the error ie that you have an invalid assignement.
This is because in your conditional statement you are using an assignement operator = instead of a comparison operator ==
You may want to review section 2.5 Most Commonly Used Operators in the Beginner Tutorial2: Commonly Used Core Javascript which is in the EFS KnowledgeBase in the Help Guides and Tutorials folder

I spent a lot of time trying to figure this out. I even did it the "right" way but there must have been some other things wrong so I did not get it.

I reread the section you referred me to and applied and it worked on the first change. Some of the simpliest things can give me the biggest problems (but I won't make this mistake again!).

Once again, a big thank you Alex for straightening me out.
