use an option value when updating it

Add attribute to your option set that is of type text. Name it country code. Add the appropriate country code value you to it.

Then for the option set to match the value from the SQL connector, use ‘get option’ then all options of the type you want then use filter and constrain by this options country code is equal to the SQL connector value (I think your step 10) and choose first item. Just make sure you don’t create more than one option with the same country code.

That way you are matching text against text in the filter to arrive at the option value needed for the field that is option value.
