Basic Mission 4

Hello Everyone..
Firstly, sorry to post in here...for some reason I couldn't post in the actual basic mission forum where this question rightly belongs.
Secondly..I cant say in great detail what my question involves as it includes too many spoilers! but basically I solved the problem and completed the mission. However, because I am new to all this I am not actually sure how I did it!!. By this I mean that the method I used to obtain the password threw up an unexpected result which I hadn't counted on..
Would anybody like to go through this with me so that I can understand what I did right!!
Cheers
