codes/scripts and template changes Options

[Rubby_Dubby]

I just switched from xanga to blogger b/c my xanga was getting too messy and too many people wwere messing with it. I know where to put codes on xanga and a little abotu editing them, but i an utterly confuse don what to do on blogger.

I know from reading other posts that i have to put them in the template section, but i dunno where. Do i put it at the end? In the body?

i also dont' know how to change my template to one of the other premade noes that were choices at the beginning. I was wondeirng if anyone knew the codes for them

ok-thanks for helping!
