How to check multicollinearity in Pooled Least Squares?

[Nuantip]

Hello

I'm using panel data with Pooled Least Squares (Fixed Effect) but I don't know how to check multicollinearity in Pooled Least Squares.
In Eviews 6, I click Quick --> Group Statistics --> Correlations, Then I type equation in Series List, for example, logfdi? logfdi?(-1) loggdp? logwage?
After that, Error message said that logfdi? logfdi?(-1) loggdp? logwage? is not defined.
So, I don't know how to check multicollinearity. Could you please help me?

Thank you in advance.
