One trigger to activate two functions - google-apps-script

Question

Self taught noob, working in google sheets, sorry in advance for the mess here. I am trying to pull data from two cells into a new sheet. Both of these are pulled in after I trigger them with an onEdit. I need to enter a value and hit enter on both cells for them to be placed into the new sheet. How would I set this up so that when I trigger "D9" I would pull in "C9" plus "D9"?
function onEdit(e){
// Set a comment on the edited cell to indicate when it was changed.
if(e.range.getA1Notation() === 'C9'){
var input = e.range.getValue();
var sheet = SpreadsheetApp.getActiveSpreadsheet();
var inputSheet = sheet.getSheetByName("input")
var masterSheet = sheet.getSheetByName("master inventory");
var currentRow = inputSheet.getRange("E9").getValue();
masterSheet.getRange("A3:A1000").getCell(currentRow, 1).setValue(input);
inputSheet.getRange("E9").setValue(currentRow, 1);
}
if(e.range.getA1Notation() === 'D9'){
var input = e.range.getValue();
e.range.clearContent();
var sheet = SpreadsheetApp.getActiveSpreadsheet();
var inputSheet = sheet.getSheetByName("input")
var masterSheet = sheet.getSheetByName("master inventory");
var currentRow = inputSheet.getRange("E9").getValue();
masterSheet.getRange("B3:B1000").getCell(currentRow, 1).setValue(input);
inputSheet.getRange("E9").setValue(currentRow + 1);
}
}

I am not sure exactly what you are trying to do, but try this:
function onEdit(e) {
var x=e.source.getSheetName()
if( x == "input" ) { //checks that we're on the correct sheet
var y = e.range.getSheet().getActiveCell();
var z= e.range.getSheet().getActiveCell().getA1Notation()
var row=e.range.getSheet().getActiveCell().getRow()
if(z=="D9" && x=="input"){
var cell=e.range.getSheet().getActiveCell().getValue()
e.range.getSheet().getActiveCell().clearContent()
var nextCell =e.range.getSheet().getActiveCell().offset(0,-1).getValue()
e.range.getSheet().getActiveCell().offset(0,-1).clearContent()
var sheet = SpreadsheetApp.getActiveSpreadsheet();
var masterSheet = sheet.getSheetByName("master inventory");
masterSheet.getRange("A3:A1000").getCell(row-2, 1).setValue(nextCell);
masterSheet.getRange("B3:B1000").getCell(row-2, 1).setValue(cell);
