title: Loop through Textboxes in access database
body: <p>I have an Access database that I want to loop through certain textboxes in order to do a calculation and display the answer in a seperate textbox. When I attempt to loop it loops through every control on my form (with the Form.Controls) method. I would like to only loop through 4 specific textboxes (txtbx1, txtbx2, txtbx3, txtbx4) when my button is clicked. </p>
  
  <p>Explanation... 
  TextBox_A contains a Number 
  Upon button click take the number from TextBox_A, Multiply by 2800, then Divide by 12
  Display the answer to the calculation in txtbx1. </p>
  
  <p>I would do this for each of the 4 textboxes named above. Then have a "Total" textbox that adds up the total from each textbox (txtbx1, txtbx2, txtbx3, txtbx4). Please help, new to this and at a complete loss. </p>
