@Nived_Nambiar 's suggestion is a good idea if your list is not really a list, but instead a data table with columns. It's just missing some parameters in the statement.
It could be done like this:

Or, if you reverse this to use StartsWith() then you need to put in %False% in the second operand.
It's a bit hard to understand what it is that you are trying to achieve here, without really seeing some sample screenshots of your flow and your data. It would be great if you could show us what the values of the list look like during runtime.
@MichaelAnnis , it can definitely be done with an OR statement and there is no need to build nested Ifs. It just needs to be done right based on the underlying data.
