title: Mining for dates with HLOOKUP-formula
body: <p>I have a google sheet where I need to, i think, use the HLOOKUP-function. I do not however have enough knowledge to make it happen.
  <br>
  I have a huge sheet, where I would like to collect a start date, from "SW" or "SWF".
  In the cells B2:HB2 I have dates correctly formatted.
  In the cells B5:HB5 I have text with "SW", "W", "SWF" and "WF".
  <br><br>
  If the formula finds "SW" or "SWF" I would like it to give the date on the same column. 
  So if the formula finds "SW" in cell D5, i would like it to show me the date in D2.
  <br>
  I hope someone has knowledge to make this formula and help me understand it =)
