title: How to subtract user inputted value in a specific table value?
body: <p>For Example lets say I have a table created name 'Budget' and column 'funds'.  when a user inputted a value in a VB form, it will save in registration table in the 'amount' column and the value inputted in that will be deducted in the 'funds'. I tried this but failed.  </p>
  
  <pre><code>Update 'Table Name' SET Funds = (Funds - 'Value inserted')
  </code></pre>
