How to Change .getMergedRanges() From String to a Range? - google-apps-script

Question

The following code will run very slow in my Google Sheets because my getRange is too large. Is there a way to only loop through the columns that are merged? I only want the for loop to get the number of columns in "yourRange" that are merged.
function getUpfrontCosts() {
var sheet = SpreadsheetApp.getActive().getSheetByName('LPB_COST');
var cl , count=0;
var yourRange = sheet.getRange("H13:UV13");
for (var i = 1; i < yourRange.getNumColumns()+1; i++)
{
cl=yourRange.getCell(1, i);
if (cl.isPartOfMerge()){
if (cl.offset(15, 0).getBackground() == "#ff8300" && cl.getMergedRanges()[0].getCell(1, 1).getValue()=='Upfront Costs') {
count = count + cl.offset(15, 0).getValue();
}
else {
}
} else {
}
}
return count;
};
The second code is how I am trying to turn a string to a range. I am getting "Cell reference out of range" error
How can I change cl to not be a string and be a range?
function getUpfrontCosts()
{
var sheet = SpreadsheetApp.getActive().getSheetByName('LPB_COST');
var destSheet = SpreadsheetApp.getActive().getSheetByName('Top Level PN');
var cl , count=0;
var yourRange = sheet.getRange("I13:UZ13");
var mergedRanges = yourRange.getMergedRanges();
for (var i = 0; i < mergedRanges; i++){
}
var newRange = sheet.getRange(mergedRanges[i].getA1Notation());
Logger.log(newRange.getA1Notation());
for (var i = 0; i < newRange.getNumColumns()+1; i++){
cl=newRange.getCell(1, i);
Logger.log(newRange.getA1Notation());
if (cl.offset(15, 0).getBackground() == "#ff8300" && cl.getValue()=='Upfront Costs') {
count = count + cl.offset(15, 0).getValue();
}
else {
}
}
return count;
};
This is the line with the error
cl=newRange.getCell(1, i);

if you want to use merge cell range, you can do this:
function UntitledMacro1()
{
var sheet = SpreadsheetApp.getActive().getSheetByName('Sheet1');
var cl , count=0 ;
var yourRange = sheet.getRange("I13:UZ13");
var bb = yourRange.getMergedRanges();
for (a=bb[0].getColumn();a<bb[0].getLastColumn()+1;a++)
{
//Your actual columns from I13, for first merge range, here your cl,
//but if your range is ("13:13"), you don't need
//-sheet.getRange("I13").getColumn()+1
cl=yourRange.getCell(1, a-sheet.getRange("I13").getColumn()+1);
//For your offset 15
Logger.log(cl.offset(15, 0).getValue());
//on so on
}
};
