You can actually read the summarised progress here on how it how far it has progressed.
Over here, I would like to share what I have learned in my most recent attempt to make full use of Google Sheets (which can be viewed in public for the benefit of transparency).
@aikido.hung would have been proud of me, but then again, to him it is just easy peasy; because he is the master of Spreadsheets!

I would believe that most of the time we are very much used to the basic use of Google Sheets (or Excel Spreadsheets), and most of the time (like me, maybe not you) would probably just manually fill in everything that needs to be filled in; and this usually could cause human error compilation.
I however did use a very manual style to do this (until I perfect it in the future), but if you noticed that different "X" mark in the cell produces different cash value.
A very good example is the application if the order requires express postage poslaju .
A t-shirt that is 2XL and below all comprises of MYR 23 in total for full customised printing of a t-shirt with at least 6 colours on it; but if a buyer request for a postage service, if you do not use a formula to do so, you will end up having doing all the calculations manually, where you can make mistakes.
Therefore, in every cell in column N (Total Price), this rule was applied:

I figured a screen capture will work better as there are colour codes to it
This applies to those who used cash sales, and if there is and indication of "Y" in cell L (That includes poslaju services) it will add an extra MYR 9 into the service charge (including packaging)



Leave the to range number unfilled so that the system will intelligently fill up the default range for you; otherwise you will need to specify yourself.

This is where the magic happens. At the value of formula you would need to write in your specific thing to look into; BUT, so far, as I have not used the IF statement yet, you should specify a simple value only instead of complicating things because one range of cell can actually receive multiple rules to look into (sequentially)

Notice that I only specify one cell as a reference to look into ?
There were countless times I tried to set it as a range to spot for the word "Sabah"; but often times it gave me an error.
After vigorous searching thanks to Presearch that gives more unfiltered search results compared to using Google search directly; I found out that somehow because of the range I have set to look on, each of the row in column U (for example) will automatically counter check each row in column R.
Notice that I put a $ before R? That is because I only want the rule to check on nothing but column R; otherwise the whole formula will go crazy because it will check the entire range including the application range U.

After that, you can just apply the style you want exactly as you wished so that it will show just like what you want.

I have not tried adding multiple match conditions into the formula just yet; but if you already know about it, do share your comments or even point me to your post if you already have written one.
Knowledge is power and sharing is wealth. Sometimes we keep the things we learn so much to ourselves we ended up overloading our lives with unnecessary burden when people come and try to ask you for help.
These are already quite common and humans should not race and compete with each other, but instead offer ourselves in terms of service to those who truly need help and perhaps, from that point, our validated characteristics will win the hearts of more than what we can charge them for, and that, actually generates more wealth than you can think of.Anyways, enough with the philosophical part above. I hope from this post you have learned a neat trick or two to impress not only your bosses but make your lives easier, as much as this discovery helped me so much!
