# Excel/Excel Arrays

Advertisement

Question
Hi Tom,
I have recently started exploring Excel and have run into a problem. Just last week, I didn't know what arrays were, but i have come to better understand them these last few days. Understanding (admittedly to a limited degree) arrays have opened many useful doors including the use of the index function to make dynamic charts. An example of a formula I am working with is included below:

=INDEX(Room,SMALL(IF(OR(Status=\$AA\$1,Status=\$AA\$2),ROW(Room)-ROW(\$N\$6)),ROWS(B\$7:B7)))
**"Room" is defined as \$N\$7:\$N\$25
**"Status" is defined as \$O\$7:\$O\$25
**"\$AA\$1" contains the text "Inhouse"
**"\$AA\$2" contains the text "Out"

I was wondering if there was a way to consolidate the OR(Status=\$AA\$1,Status=\$AA\$2) section, just in case I wanted to have Status=\$AA\$3, Status=\$AA\$4, etc. I would really prefer not to type each out and was wondering if there was a way this could be avoided.

Answer
Jay,

You could do

ISNUMBER(FIND(Status,\$AA\$1&\$AA\$2&\$AA\$3&\$AA\$4))

to replace your OR statement.

=INDEX(Room,SMALL(IF(ISNUMBER(FIND(Status,\$AA\$1&\$AA\$2&\$AA\$3&\$AA\$4)),ROW(Room)-ROW(\$N\$6)),ROWS(B\$7:B7)))

But if you meant could you do

OR(STATUS=\$AA1:\$AA4)  then the answer would be no.
