I am very new to JavaScript so please forgive the question if easy.

I have created a Google Sheet. I have used the first tab called Form, to create a data entry form, this data is then saved, using JavaScript to another tab called, Removal_list. All works fine. I have added a search function to recall the data from the Removal_list to Form using names. What I cannot work out is how to show not just the first object that meets the criteria. Example, I will have a list of names (column B in the sheet), which can be duplicated. When I search it will only return the first occurrence. What I would like is the search to allow me to see each occurrence, one at a time. So if John Smith is in my list five times, the first occurrence will populate (as it does now), if this is not the one I want to see then, I somehow, move on to the next occurrence.

// search values

var SEARCH_COL_IDX = 1
function Search() {

  var ss       = SpreadsheetApp.getActiveSpreadsheet();

  var formS    = ss.getSheetByName("Form");

  var valuesFound = false;

  var str = formS.getRange("D18").getValue();

  var values = ss.getSheetByName("Removal_list").getDataRange().getValues();

  for (var i = 0; i < values.length; i++) {
      var row = values[i];

      if (row[SEARCH_COL_IDX] == str) {
        

                 formS.getRange("B5").setValue(row[0]);
                 formS.getRange("B7").setValue(row[1]);
                 formS.getRange("B9").setValue(row[2]);
                 formS.getRange("B11").setValue(row[3]);
                 formS.getRange("B13").setValue(row[4]);
                 formS.getRange("B15").setValue(row[5]);
                 formS.getRange("E5").setValue(row[6]);
                 formS.getRange("E7").setValue(row[7]);
                 formS.getRange("E9").setValue(row[8]);
                 formS.getRange("E11").setValue(row[9]);
                 formS.getRange("E13").setValue(row[10]);
                 formS.getRange("E15").setValue(row[11]);
                 formS.getRange("G9").setValue(row[12]);
                 formS.getRange("G11").setValue(row[13]);
                 formS.getRange("G14").setValue(row[14]);
                 valuesFound=true;
                 return;
     
  }
            if(valueFound=false){

            var ui=SpreadsheetApp.getUi();

            ui.alert("No record found");

          }
  }}
