Lookup Setfilter based on another field on the form

Lookup Setfilter based on another field on the form

Hello,
          I came across your tool  just today. Seems interesting but i would expect a lot of improvments before i spend money to buy it.
 Please help me with this situation. I have 2 field for names on the form. I get to choose a name from the lookup of Names for the first field. For the second one i will want the same look up minus the name on the field field.
 
1) My thoughts. I should be able to filter it out
2) I should be able to create a list after the first name is entered ( Everything minus that name )and use it as a Lookup for the second field.
3)    Do some deluging someplace.
 
Unfortunately i'm frusted trying to do any of these. I need some guidence and encouragement here please.
