Portfolio table br problem

Hello, i got a problem with the portfolio post template. Whenever i put in a table(maybe other html tags too) i get alot of (br)’s infront of it, i already looked up the code and it seems the problem arises here:

echo str_replace(“\n”, “”, $full_descr);

When i change that into : echo $full_descr it removes the but breaks the overal /n to function.

Is there any way to solve this? I already looked up the wordpress formatting, but it seems it has nothing to do with this.
