If you are a new developer in FiveM, you can read the FiveM Documentation to get a good start.

ESX.UI.Menu.CloseAll()
ESX.UI.Menu.Open('dialog', GetCurrentResourceName(), 'menuName', -- Change menu name
{
  title = ('Your Title Here')
},
function(data, menu)
  local amount = tonumber(data.value)
  if amount == nil then
    ESX.ShowNotification('Invalid Amount')
  else
    -- Here you put the function you want to perform.
    -- To take text values use: data.value 
    -- To take number values use: amount (declared above)

    menu.close()
  end
end,
function(data, menu)
  menu.close() -- Action when closing the menu 
end)
