Google Apps Script For loop not repeating inside while loop - google-apps-script

Question

I have long code wherein there is a while loop and inside that while loop there is a for loop and then an if statement. I want that for loop to run again and again until condition of the while loop is fulfilled. Although, that If statement keeps repeating under while loop I am not understanding why that For loop only runs once and never repeats. Please guide what is wrong in the code;
while(affDisc == 'NotClr'){
//Finding affiliate discount row
for(var i = 20; i <= odrEn && slsRprtSh.getRange('I' + i).getValue() > 0 && slsRprtSh.getRange('J' + i).getValue() == 0; i++){
Logger.log(vndr + ' ' + i);
Logger.log(minOdrRw);
if(minOdr == 0){
minOdr = slsRprtSh.getRange('I' + i).getValue();
minOdrRw = i;
}else if(slsRprtSh.getRange('I' + i).getValue() < minOdr){
minOdr = slsRprtSh.getRange('I' + i).getValue();
minOdrRw = i;
}
}
//check if applying discount in minimum order fits here
if(aggFloor - runinFloor > runinFloor + minOdr * .05 - aggFloor && slsRprtSh.getRange('J' + minOdrRw).getValue() == 0){
Logger.log('runfloo ' + runinFloor);
//return false;
slsRprtSh.getRange('J' + minOdrRw).setValue(minOdr * .05);
slsRprtSh.getRange('J' + minOdrRw).setNote('5% discount for affiliate commission');
slsRprtSh.getRange('L' + minOdrRw).setFormulaR1C1('=R[0]C[-3]-R[0]C[-2]');
slsRprtSh.getRange('M' + minOdrRw).setFormulaR1C1('=R[0]C[-1]*0.15');
slsRprtSh.getRange('N' + minOdrRw).setFormulaR1C1('=R[0]C[-1]+R[0]C[-2]');
apldDisc = apldDisc + minOdr * .05;
runinFloor = runinFloor + minOdr * .05;
}else if(aggFloor - runinFloor < runinFloor + minOdr * .05 - aggFloor){
affDisc = 'Clr';
}
}
