title: Searching Multiple strings with 1st criteria, then searching those returned values with a different criteria and so on
body: <p>so..</p>
  
  <p>I have a txt file with hundreds of sentences or strings.</p>
  
  <p>I also have 4 comboboxes with options that a user can select from and
  each combobox is part of a different selection criteria. They may or may not use all the comboboxes.</p>
  
  <p>When a user selects an option from any combobox I use a For..Next statement to run through the txt file and pick out all the strings that contain or match whatever the user selected. It then displays those strings for the user to see, so that if they wanted to they could further narrow down the search from that point by using the 3 remaining comboboxes making it easier to find what they want.</p>
  
  <p>I can achieve this by using lots of IF statements within the for loop but is that the only way?  </p>
