I used this query after studying from Google:
=QUERY(IMPORTRANGE("https://docs.google.com/spreadsheets/d/1_Mh5lEqBh1OBzuW5U1Fvr1MK_6doIvKmV23YKp4Fu0c/edit#gid=529591601","'iOS'!E:G"), "Select Col4",1)
I am getting the error as follows:
Unable to parse query string for Function QUERY parameter 2: NO_COLUMN: Col4
What should I do for it?
