Google Sheets: delete rows containing specified data - button

Question

I'm new to Java scripting and Google Apps Scripts so i am sorry if this has already been answered. I was not able to find what i was looking for over the last few months of working on this project.
I am working on a variant of the scripts here:
Delete row in Google Sheets if certain "word" is found in cell
AND
Google Sheet Script - Find Value in Col and Delete Row
I want to create a button, or menu, that will allow someone to enter specific data, and have each row in the spreadsheet containing that data deleted.
I have a test sheet here that illustrates the data i'm working with, formulas i'm using, and has the beginning of the script attached to it:
https://docs.google.com/spreadsheets/d/1e2ILQYf8MJD3mrmUeFQyET6lOLYEb-4coDTd52QBWtU/edit?usp=sharing
The first 4 sheets are pulling data from the "Form Responses 1" sheet via a formula in cell A:3 in each sheet so the data would only need to be deleted from the "Form Responses 1" sheet to clear it from the rest of the sheets.
I tried working this in but i do not think i am on the right track.

I also posted this on Google Docs Help Forum 60 days ago, but have not received any responses.
Any help would be greatly appreciated.

There's a few steps. For usability of UI this takes a little longer code. In concise form:
The user activates a dialog and enters a string.
Rows w/ the string are deleted (with error handling and confirmation)
(Hopefully this gets you started and you can tailor it to your needs)
Function that initiates the menu:
function onOpen(){
SpreadsheetApp.getUi()
.createMenu('My Menu')
.addItem('Delete Data', 'deleteFunction')
.addToUi();
}
The main workhorse:
function deleteFunction(){
//declarations
var sheetName = "Form Responses 1";
var ss = SpreadsheetApp.getActive();
var sheet = ss.getSheetByName(sheetName);
var dataRange = sheet.getDataRange();
var numRows = dataRange.getNumRows();
var values = dataRange.getValues();
var delete_string = getUIstring();//open initial UI, save value
if (delete_string.length < 3) return shortStringError()//UI to protect your document from an accidental entry of a very short string.
//removing the rows (start with i=2, so don't delete header row.)
var rowsDeleted = 0;
for (var i = 2; i <= numRows; i++){
var rowValues = values[i-1].toString();//your sheet has various data types, script can be improved here to allow deleting dates, ect.
if (rowValues.indexOf(delete_string) > -1){
sheet.deleteRow(i - rowsDeleted);//keeps loop and sheet in sync
rowsDeleted++;
}
}
postUIconfirm(rowsDeleted);//Open confirmation UI
}
Isolated UI functions to help make above function more concise:
function getUIstring(){
var ui = SpreadsheetApp.getUi();
var response = ui.prompt("Enter the target data element for deletion")
return response.getResponseText()
}
function postUIconfirm(rowsDeleted){
var ui = SpreadsheetApp.getUi();
ui.alert("Operation complete. There were "+rowsDeleted+" rows deleted.")
}
function shortStringError(){
var ui = SpreadsheetApp.getUi();
ui.alert("The string is too short. Enter a longer string to prevent unexpected deletion")
}

I'll just show a way to delete the cell value if it matches your search criteria. It's up to you to connect it to buttons ,etc.
You'll loop through a Sheet Range. When you find the word match, delete it using clearContent()
function deleteSpecificData() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];
var range = sheet.getRange("Sheet1!A1:C4");
var values = range.getValues();
var numArray = [1,2,3,4,5,6,7,8,9];
var deleteItem = "Garen";
Logger.log(range);
for(var i=0; i< values.length; i++){
for(var j=0; j<values[i].length; j++){
if(values[i][j] == deleteItem){
var row = numArray[i];
var col = numArray[j];
var range = sheet.getRange(row,col).clearContent();
}
}
}
}
