Import Range Selecting Range [Google Sheets]

Hey,
I am putting in an import range on google sheet which will import data from a different google worksheet, but I am having trouble selecting the range.
I need the range to be From A to F and AB , how can I add the AB row into the import range to pull data from AB Row.

See attached screenshot for formula:

I haven't as yet found any syntax that works with IMPORTRANGE, but you can always return the entire range and then wrap that in a QUERY call:

=QUERY(IMPORTRANGE(url, entire table), "Select Col1, Col2, Col3, Col4, Col5, Col6, Col28", -1)

Have you tried "A:F, AB:AB" for the second argument of IMPORTRANGE?

Yep. Did it work for you?
