How do I display text based on a condition?

I feel like I'm missing something here but can't find out what. I'm creating a planning template. I want a separate table in which the user can put the deadline name with the deadline week.

In my planning overview I want these deadlines to appear. To do this I tried an approach with IF-statements. Although this works well it doesn't deal with a new deadline that is added later on in the project. I could brute force this and create 30 IF-statements so there's space for 30 deadlines (which is more than enough) but I have a feeling this can be done in a much smoother way. Do you have any suggestions for this?
