Ahh 3mm Aluminium Checker Plate and 2mm Stainless, I love Checker plate Best sheet ever for Bed linings or doors. That stuff takes a kickin and keeps on ticking.
However I hate spreadsheets so I wish you the best of luck, Doing My accounts every month inspires about 3 hours of procrastinating, 2 pots of coffee and finally a whole lot of the Big F word and a few C U Next Tuesdays.
Eventually the spreadsheet is finished and a brief moment of self satisfaction until I remember I have to do the same thing next month.
Let me know how the course goes, might even try one myself if it saves me headaches.
Haha, a few F's and C"s...I get it.
I'll be honest and say I know a little already, self taught, but everything I do is probably happening the long way and so I don't know what I don't know. A company paid course to unfuckerise my Exel skills seems prudent.
I will let you know how it goes and whether it was worth it.
