Donavon,
I'm wondering if you could some how use the Search function to determine how many spaces there are in each row, then use that number from your search column to split the column. I just don't have the right logic determined to do this.
A longer option might be to create three numeric Left function columns for a lengths of 6, 7 and 8. Then use if functions to compare the sizes of the numbers against each other for the greatest one. Then keep that value.
Sorry those are two ideas off the top of my head.
