Thanks - is there a way to do it so that they are separate snippets of data (ideally as a label similar to the multiple select) rather than as a string?
The ideas from @Adam_C certainly work, but I want to suggest a different approach. It seems that the question of “short” vs “long” – what I’ll call Term Length Category – and the number of weeks/months are different types of information and should therefore be in different fields. One of the tenets of DB design is that every different type of information should be separate.
This is a similar situation to something I have at work – we produce multiple types of written products, each of which has attributes which need to be in the product’s record. Based on that experience, I suggest:
Create a new table: Therapy Terms.
Give it fields:
Term Category. Single Select, values: Long or Short.
Therapy Length. Single Select, values: 5-6 weeks, 1-2 weeks, 12 weeks, etc. for each of the potential situations people can have
Name: Formula that combines the two fields concatenate({Term Category},if({Therapy Length}," - " & ({Therapy Length}))
Create an entry in this table for each of the combinations you may have, ie, each of the products you offer. So Short Term-1-3 weeks, Short term-12 weeks, etc.
Link Your Existing table to Therapy Terms and allow multiple selection of Terms.
In your existing table, create two lookup fiends - one for Term Category and One for Term Length.
The result:
You have a menu of Therapy Terms to choose from for each patient, and the record will show a Term Category of “Short” or “Long” or “Short, Long” and in a separate field you have the Therapy Length of “1-4 weeks” or whatever.
It’s easy to add new options to the menu without messing with the main table field settings.
You get the fields you want in the main record.
It reduces the chance of data input error by enforcing a set of options. It’s less possible to input impossible/incomplete combinations in your day to day work – you don’t create “Long Term, 1 week” option or “Short term, 2 years” options.
This also has the additional benefit of giving you the ability to have other ‘attributes’ that a type of therapy can have and show in the main record.
