I'm trying to figure out how to parse this google sheets function:
=IFERROR(QUERY($A$2:$F$1000, "select F where A="&A4&" "),"")
I'm having trouble understanding the "select F where A="&A4&"
part. The function is applied to an entire column. For some of the rows, this function returns a number, for others it returns a blank. The A column which it is referencing is entirely composed of 6-digit numbers.
What is going on such that sometimes the function returns a number and sometimes a blank?
Also, why are the ampersands important? If I take away the ampersands, the function returns an error.
