Capstone Fundamental Ex 1.5
refServiceHandle: hopen `::5010
**1.5 Using the handle `refServiceHandle` and the `uniqueOpts` variable we created before, call the
`getOptionRef` API and retrieve the associated Options Reference data. Store the returned table
in a variable `optRef`.**optRef: refServiceHandle(`getOptionRef;uniqueOpts)
Using this line of code is not working. IPC says blocked. How do I fix it?

I notice for your uniqueOpts variable you’ve declared it as:
uniqueOpts: enlist (select distinct option_id from trade)
Tables are created out of lists, so by enlisting the option_id column you are creating a list of a list.
Since we already have our list, we just want to convert this into a list format. To do this you can use the exec keyword.
Once you’ve edited this, it should work fine.
Thanks,
Megan
