How do I create a 'risk assessment' custom field automatically filled from manually created and filled risk likelihood and risk consequence (each of these fiels having 5 options)

[J Thomas]

We've done this using a Calculated Number Field which is in the JIRA Misc Custom Fields plugin.

Our calculation multiplies the values in the custom fields 'Impact' and 'Likelihood', which are select lists with options 1,2,3,4 so we have to cast the values from strings to numbers before multiplying them. 1=lowest, 4=highest so the minimum risk score is 1 and the maximum is 16.

Note that Calculated Number Fields are only visible when viewing an issue, not when editing it.
