Formula for conditional rule to make row change colour over multiple sheets

Hi,

I want to change the colour of rows depending on the letter that is in a column. I want it to do it over all the sheets of the document. In the G column there will be letters like 'W' and 'L' that signify something and I want to make it clear by changing the row colour fill. I've tried a few formulas I found by googling but they didn't work. I should point out that the letters are connected, so if I put a 'W' on the second sheet it appears on the first sheet as well. Is this possible?

Thanks!

thank you will give it a go!
