Enable the Gravity Gun.
Portal gun will not load unless gravity gun is in.

Also, use spaces after punctuation, like I have.

Thanks,and sorry about my grammar. It's usually quite-- average, you may say. Never knew about the space thing,but thanks for telling me!

Punctuation includes commas, colons and semicolons as well.

Make sure you use two spaces after periods, it's the proper format.  Also, it's not grammar, more of sentence structure.
