I first want to thank all those than emailed, me or added appropriate sympathetic comments in regards to the destruction and rebuild of my blog page. As we Speak, Wayne John is going through his own hell, in that his server has gone haywire---which makes my little incident look like a stubbing one's toe. Lets all hope Wayne rejoins the living soon.
In any case what I wanted mostly to say here was. The lesson I learned is----before ya get to frisky experimenting with your blog sites---make a copy of what ya got before ya start modifying anything. Once ya have that copy safely tucked away elsewhere on your computer, you can play with your blog page all ya want---and if ya screw it up, you just replace it with that copy you made before ya started and no worse for the trouble.
How does one make a copy of ones entire template?---well blogger makes it easy enough.
1) click on the big B in the upper right of your Blog page. (this will take you to your dashboard)
2) On the dashboard screen click on the LAYOUT Tab.
3) Now click on EDIT HTML
The screen you now are looking at, at the top suggests you save a copy of your template before you modify any code. DO SO with the button they provide. (only takes seconds), and if your not sure you can remember, write down the location your saving the file to). Now your free to roam about your template at will. Note too, should ya screw it all up, this is the same screen you want to come to so that you can upload that copy you saved earlier to put things back to the way they were.
I have made use of Blogger Talk's button generator to create a button to remind myself of this basic act of survival----
