Adtivity Duration and resource levelling

hi people,

I am new in planning, and It would be highly appreciated to answer my BASIC questions :)

• Have an activity which actually takes 12 hours but in 2 weeks, how I can plan it? already in my schedule,  it started on 17^th Feb and will finish 28^th Feb., which is 80 hours for duration that is not correct, what is planning solution for this?
• the resource who is working on above job, is working on other four tasks as well. During in 2 weeks he is working 12 hours to finish mentioned job and other 4 tasks which not finish in 2 weeks. how I can show his work hours in my plan?
• Last question: why finding is not working most of the time? To search an activity ID I use find but doesn’t work! I Mean I can find manually but in finding window it says no result!

Thanks in advance guys!

Nikan.
