title: Org Table Formatting with Dollar Sign Columns
body: <p>I'm using this method of creating a column:<br>

  <p>I have a spreadsheet with 9 columns and column 8 contains filenames which have dollar signs in them, such as:<br>
  <code>product_name $500.00.jpg</code></p>
  
  <p>So I want column 9 to state whether or not the file actually exists, so my org TBLFM is as follows:<br>
  <code>#+TBLFM: $9='(file-exists-p (concat "/import/" $8))</code></p>
  
  <p>So the issue is, whether or not I use the <code>;L</code> flag at the end of the TBLFM, when applying the formula I immediately get "Invalid Field Specifier: "$500"" because there is no column numbered 500.</p>
  
  <p>Any thoughts as to how I can get this working? I've tried $8 in quotes and not in quotes, with and without the literal flag, and I've tried escaping the dollar sign in the actual columns all with no luck.</p>
  
  <p><strong>Edit:</strong> It's important to note that changing my column values to something like:     <code>product_name $\ 500.00.jpg</code>  does in fact work, however the <code>file-exists-p</code> value returned is obviously incorrect.</p>
  
  <p><strong>Edit:</strong> An example org-mode table triggering the error:   </p>
  
  <pre><code>| foo | bar | /some/file with $500 in it.jpg |   | baz |
  |     |     |                                |   |     |
  #+TBLFM: $4='(or (file-exists-p $3) "f")
  </code></pre>
