After watching the TempVars video, I have spent three full days trying to apply some of the capabilities to a database without success.
In frustration I looked away and watched the 'Scope' video and light bulbs flashed all around.
Our esteemed instructor, Mr Richard Rost always makes reference to the Pre-Requisites at the start of every video. I have learnt the hard way that this can be very important to the full understanding of what he is trying to teach us.
Perhaps 'and don't ignore Pre-Requisites' could be added to Live Long and Prosper haha
