Or you can just get rid of the panel id and just put the coding in each section if you already have them separated.
I'm sure there's an easier way to do this sort of thing, but this worked out for me.
Also make sure you didn't leave anything out like make sure when you're done with the code to close it by adding ";}" at the end (without the quotes of course).
Np glad I could help and that depends on how big you want the panels.
My about section is 200px for all of them so you might want to go a bit higher than that, just make sure you use the same number for each one.
