Loading data into flags

[#1]

I have a flag,

if(Match(disc1, '101', '102') and year(recorddate) > '2015', '1') as NewRecord.

If I want to add more values dynamically  using a input box for field disc1,  how can I do that?

I want to add value 110 to disc1, can I create a input box and do that?

So the statement will look like this,

if(Match(disc1, '101', '102', '110') and year(recorddate) > '2015', '1') as NewRecord.

Please throw in some ideas
