Shortcomings

I have decided that computer programming is not my thing.  One would think that when one downloads a template to use on one's blog that all one would have to do is copy and paste into one's edit html tab.  Not so.  The problem is I have no clue what is required so unless I have a breakthrough and become suddenly fluent in html or xml or whatever it is, my blog will be forced to keep its current template.  This would not be so bad except now that I know there is a whole world of amazing templates out there that are off limits to me simply because of my technology shortcomings, I know I will not be satisfied.  Oh to be a tech nerd!
