Problem with environment variables

Hello, I installed the intel compiler without much problem, but I'm having some problems with the variables

I did run the script like this:

source /opt/intel/bin/iccvars.sh ia32

Then I can run the compiler with no problems, but always when I exit the terminal I have to run the iccvars.sh script again because the terminal says that he won't find the icpc command.

I guess it's a problem with the variables, but I can't figure out what problem it is

Thanks in advance
