Calling all Excel boffins... 
I'm 99% to where I need to be but can't figure this last bit out. I want to return blank rather than #N/A if a match can't be made. Here is formula so far:
{=INDEX(NovResults,MATCH(E2,November!$A$11:November!$A$17&" "&November!$B$11:November!$B$17,0))}
I've tried:
{=IF(ISERROR(INDEX(NovResults,MATCH(E2,November!$A$11:November!$A$17&" "&November!$B$11:November!$B$17,0))),"")}
Which almost worked as it turned all errors in to blanks, but also made the legitimate matches return FALSE.
...help!
