Hierarchy

[#1]

I am having an issue with Hierarchy.  My script will take our product Hierarchy and break it out to 5 levels, Level 1 through Level 5.  So lets say my product hierarchy field is up to 10 char and each individual level is 2 char.  So, if the field value has 10 char in it, each Level will have 2 char in it and if the product hierarchy field only has 2 char in it, then only Level 1 will have 2 char in it and there will not be a Level 2-5.  The issue that I have is in making selections with a button.  I set a button to select values from Level 1 and to exclude certian values from level 2.  Trouble is, if one of the values in Level 1 does not have any values in Level 2 it is dropped from the selection since there is no coresponding Level2 value.  Since many of my prod hierarchy's do not go out to Level 5, how can I account for this in my script so my selections are not dropped?

Below is the script in the data model.  I did not write this and I have never worked with Hierarchy in QlikView so any help on this topic would be appreciated. 

Thanks,
