Troubles with for loop and Range - for-loop

Question

var colRange = getRange("Sheet1!G2:G200")
logger.log(colRange)
logger.log(colRange[0])
for(var i = 0; i < colRange.length; i++) {
if(activeCell.getColumn() == 7 && activeCell.getRow() == colRange[i] && ss.getActiveSheet().getName()=="Sheet1") {
newValue=e.value;
oldValue=e.oldValue;
if(!e.value) {
activeCell.setValue("");
}
else {
if (!e.oldValue) {
activeCell.setValue(newValue);
}
else {
activeCell.setValue(oldValue+', '+newValue);
}
}
}
}
Could anybody help with the for loop. Need it to check every row of column G to allow multiple drop down selections. If I replace colRange[i] with the specific row it does work. I assume I need to loop through each range G2, G3, G4, etc

Please explain what you are trying to
It's hard to figure out what you are trying to accomplish with you code but this is my best guess
function onEdit(e) {
const sh = e.range.getSheet();
if (e.range.columnStart == 7 && e.range.rowStart > 1 && sh.getName() == "Sheet1") {
if (!e.value) {
e.range.setValue("");//doesn't make sense it's already null
} else if (!e.oldValue) {
e.range.setValue(e.value);
} else {
e.range.setValue(oldValue + ', ' + newValue);
}
}
}
