GetValue ( ValueListItems ( Get ( FileName ) ; "YourValueListNameHere" ) ; 1 )
But test this carefully. Since it's a conditional value list, you may not yet have the value in place that controls what values will appear in the conditional value list at the time that this expression evaluates. You may need to use this expression in a set field script step instead of an auto-enter calculation.
Thanks Phil. I'll try that out later.
That is working. Thanks a lot Phil.
