How to pass a variable from an onEdit(e) function - google-apps-script

Question

I have two scripts that run individually, but I can't seem to merge them together correctly. I am attempting to use the onEdit(e) function to capture the row of the cell that is edited, then used that row number to amend a different sheet.
function onEdit(e) {
if (
e.source.getSheetName() == "GPS" &&
e.range.columnStart == 10 &&
e.range.columnEnd == 10 &&
e.range.rowStart >= 4 &&
e.range.rowEnd <= 5000
) {
var range = e.range;
var row = range.getRow();
var change = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var url = change.getRange(row,1,1,1).getValue(); //How to use this variable????????????
function toMaster(change,row){
var dest = SpreadsheetApp.openById('destinationsheetidxxxx')
var s = dest.getSheetByName('GPS')
var data = s.getDataRange().getValues();
var url = change.getRange(row,1,1,1).getValue()
for(var i = 0; i<data.length;i++){
if(data[i][0] == url){
Logger.log((i+1))
var range = s.getRange(i+1,10,1,1);
range.setValue('Yes')
}

Try this:
function onEdit(e) {
var sh=e.range.getSheet();
if(sh.getName()=="GPS" && e.range.columnStart==10 && e.range.columnEnd == 10 && e.range.rowStart >= 4 && e.range.rowEnd<=5000) {
var row = e.range.rowStart;
var url = sh.getRange(row,1).getValue();
var dss=SpreadsheetApp.openById('destId')
var dsh=dss.getSheetByName('GPS')
var drg=dsh.getRange(row,1)
var data=drg.getValues()
for(var i = 0; i<data.length;i++){
if(data[i][0]==url){
Logger.log(i+1);
var range = dsh.getRange(i+1,10).setValue('Yes');
}
}
}
}
