More than one condition in a trigger

Hello!

I'm trying to create a trigger that enables me to select the correct amount of Oxygen delivered (ie. 24%), after I have selected the correct delivery method from 'Face mask',  'naso-specs' or non re-breathing reservoir mask'. In one particular scenario I want to choose 24% of oxyen to be associated with  one selection of the possible correct delivery methods: 'face mask' or 'naso-specs'. However, when selecting non re-breathing reservoir mask this would count as wrong.

Moreover, the outcome would turn out wrong if the oxygen delivered does not match 24%.

Is the above possible? If anyone has a simple, clear suggestion it would make my day. :-)

Thanks
