OK Jim;

Here is the code I wrote. It is embarassing to share but done nonetheless.
Sorry it took me a day to reply.

Sub DynValidList()

Next i

PikRow = Range("Col_Lables_Row").Row + 1
PikCol = 0
PikCol = ActiveCell.Column

NumAryBlanks = 0

' from the DynList Array replacing items with ("") blanks.

DynList(LineInDyn) = ""
End If
Next i

' Remove Blanks from interior of DynList Array by placing
' blanks at the end of the Array by shuffling all items upward.

Dim k As Long
For j = 1 To NumAryItems Step 1

Loop
DynList(j) = DynList(j + k)
DynList(j + k) = ""
End If
Next j

NumAryBlanks = NumAryBlanks + 1

Exit Sub

End If

End Sub

Hi;

I have written a procedure that works; but it is long, convoluted and
probably unstable i.e. ugly. I am looking for help writting a more
appropriate set of code.

Problem:

Out of a large spreadsheet I have six columns that contain jobs to be filled
by people. Each column represents a different date, so the procedure must
start over at the beginning for each date/column.

I want to use the Valitation drop down in the cells below the label for each
column.

I have a list of jobs which can vary from time-to-time on a separate
worksheet but same workbook. The list of jobs is about 10 items long.

As the user activates each cell a list of jobs that need to be done should
dropdown showing the jobs left to be fulfilled. That is, as each job is
assigned the dropdown should show the list in a particular column but with
the jobs already assigned removed. I assume that this means the pick list
(validation dropdown) has to be recalculated as to column/date and as to
which jobs are available for each column.

As I said, I have a procedure that works, but I suspect I am not making full
use of VBA and/or formulas.

Any guidance gratefully accepted.

Regards Bill
