Hi @Jesse_Gibson - the single select field type doesn’t have a default so you can’t solve it in this way. You need a formula, but a field can’t be a formula and something else at the same time. The workaround is to create a new field (a formula) that can show “yes” or “no” based on your single select field:
The formula is:
IF({Yes/No} = 'Yes', 'Yes', 'No')
Does this work for your scenario?
