title: Excel can't find a value even though it exists within the worksheet
body: <p>this is my first post so i am sorry if this is confusing at all. I am trying to use a vLookup to run a comparative analysis between two reports. I am using a part number as a reference and trying to return the cost associated with the part from one of the two reports. So, the first issue that I encountered was due to the fact that some of the part numbers had letters in them and some didn't, so to be consistent I used the following code to clean up the part numbers:</p>
  
  <p>IFERROR(VALUE(F11&amp;C11), F11&amp;C11) </p>
  
  <p>where F11 and C11 are two components of the part number that needed to be concatenated to generate the full number. Now, the vLookup will not return anything except for #N/A for a few of the part numbers that are actually in the sheet. All of the part numbers are formatted the same for the 892 part numbers that I am searching for but get a returned value on 571 of the 892 part numbers but of the remaining 321 part numbers that did not have a return, about a third actually exist in my sheet. Lastly and for example, part number 110874402 exists in both sheets but gets a #N/A from the vLookup. When I copy the value from one sheet and search it in the other sheet using Ctrl + F, I get the following:</p>
  
  <p>(I have an image to show but apparently can't post it without a reputation of 10 or more...oops)</p>
  
  <p>The highlighted cell shows that the value exists but Excel can't find it. Does anyone have any ideas why this is or what I could be doing differently? I've been having this issue for a few months now on separate projects and haven't found any resolution.</p>
  
  <p>Thanks in advance,</p>
