Hey,
I am trying to update a filter tool based on user input and am trying to figure out the best way to go about it. My filter formula is as below:

I would like for the user to type in any amount of 6 options which would then update this formula so it can filter out what the user did not want. So far all I have is 6 action tools that update the specific string of the numbers in the above formula. I could see how you could do it if you also had 6 individual text boxes used to update each one but I would prefer something more efficient. Any help would be much appreciated.
Thanks!
