Multiple results from a single column search in a spreadsheet - google-apps-script

Question

I just wanted to know if there was a way to pull multiple (only 2 at the most) results with the code provided below. All the code is doing is searching for a user's name in a spread sheet and then displaying the value in the cell next to that user's name. The slight issue I'm running into now is that their name might appear twice in a given column and I would like for both results to be displayed. Any help would be appreciated. The full explanation of what this code is used for can be found here if needed: VLOOKUP style app script using UiApp and textBox form to reference a spreadsheet
// function called when submit button is clicked
function submit(e) {
var app = UiApp.getActiveApplication();
Logger.log(Utilities.jsonStringify(e)); // Log the input parameter (temporary)
// Write the data in the text boxes back to the Spreadsheet
var cell = e.parameter.userName;
var doc = SpreadsheetApp.openById('SPREADSHEET-ID');
var ss = doc.getSheets()[0];
var lastRow = doc.getLastRow();
var data = ss.getRange(2, 1, 2, 4).getValues();
var result = "User not found";
for (nn = 0; nn < data.length; ++nn) {
if (data[nn][1] == cell) {
result = data[nn][1];
break
}; // if a match in column B is found, break the loop
}
// Make the status line visible and tell the user the possible actions
app.getElementById('status').setVisible(true).setText(result);
return app;
}

All you need to do is modify the behavior of the search loop. Perform the search, adding finds to an array, and get rid of the break that was terminating a search after finding one item. At the end of the search, join the array of finds into a string, and you're done.
// function called when submit button is clicked
function submit(e) {
var app = UiApp.getActiveApplication();
Logger.log(Utilities.jsonStringify(e)); // Log the input parameter (temporary)
// Write the data in the text boxes back to the Spreadsheet
var cell = e.parameter.userName;
var doc = SpreadsheetApp.openById('SPREADSHEET-ID');
var ss = doc.getSheets()[0];
var lastRow = doc.getLastRow();
var data = ss.getRange(2, 1, 2, 4).getValues();
var result = "User not found";
var result_array = [];
for (nn = 0; nn < data.length; ++nn) {
if (data[nn][1] == cell) {
result_array.push( data[nn][1] );
}; // if a match in column B is found, keep going, there may be more!
}
if (result_array.length > 0)
result = result_array.join(", "); // concatenate multiple results
// Make the status line visible and tell the user the possible actions
app.getElementById('status').setVisible(true).setText(result);
return app;
}
