Change enum colour in a cluster that is in an array

Hi,

So I have this cluster with a string and an enum, that is in an array. I am using a producer/consumer event design pattern, so on the event of a mouse clicking a specific row another VI pops up with a pass/fail button and comment string.

After playing around with 'CtlRef' in the event structure I found the 'ArrElem.Value' property node that lets me find the specific array element clicked on. I can then unbundle and bundle that specific cluster. Based on the enum value of pass/fail I'd like the colours green/red respectively.

My question, how do I find the reference of a specific enum inside a cluster to change its colour based on text? I have been able to reference the cluster only. 

Thanks.

FYI, I'm using LV 2010 SP1
