a1=7 and a2=50 need formula to filter b based on values from a1 to value a2 so it would be filter(b7:b50) . if values in a1 and a2 change my filter formula also need to change how to write formula?

Hi. Forum Rule 1 is very short. It states: "Title must briefly summarize your request."

A GOOD thread title is the sort of thing you would use as a search term on Google*. Your chosen title would produce a squillion useless hits. In future, please take a bit more time to think of a descriptive title that would be "Google-friendly". Many people search the forum answers looking for help and your very general title wouldn't help them at all.

Since you are a new user of this site, on this occasion, I have changed it for you.

However, if you continue to use weak titles, you can expect to have your thread BLOCKED until you change it yourself. If that happens, to edit the thread title, open the original post, click "Edit Post" (bottom right) to access the area where you can edit your title.

*Other search engines are available!!!

Regards,

Glenn.

Maybe:

=INDEX(B:B,A1):INDEX(B:B,A2)

You seem to be using an older version of Excel than me. So, please refer to the attached file. If the formulae are enclosed within a pair of { }, these are array formulae.

These are a little different from ordinary formulae in that they MUST be confirmed in the FIRST CELL ONLY by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. After that, the array can be dragged down as normal, to cover the desired range.

You will know the array is active when you see the curly brackets { } appear around the outside of your formula. If you do not use CTRL+SHIFT+ENTER you will (almost always) get an error message or an incorrect answer. Press F2 on that cell and try again.

Don't type the curly brackets yourself - it won't work...
