Try

Dim dtTemp as Date
dtTemp = CDate(TextBox1.Text)
Set StartDate = Worksheets("Data1").Range("Z" & _
WorksheetFunction.Match(dtTemp, _
Worksheets("Data1").Range("Z3:Z600").Value, 0) + 2)

OR try the below

Dim dtTemp as Date
dtTemp = CDate(TextBox1.Text)
Msgbox
WorksheetFunction.Match(dtTemp,Worksheets("Data1") .Range("Z3:Z600").Value, 0)

Hi. Can someone please pinpoint the error in this match function statement
using a textbox which contains the lookup date to match a column of dates in
column Z. Program works if I do not use the textbox otherwise it gives a
runtime error:

Set StartDate = Worksheets("Data1").Range("Z" &
WorksheetFunction.Match(DateValue(TextBox1.Value),
Worksheets("Data1").Range("Z3:Z600"), 0) + 2)

StartDate declared as a range object.
Dates are in 3/14/01 format.
Textbox1 contains a date
Column Z is a series of dates

When I replace the textbox with a cell to contain the lookup date, the rest
of the program works. So the error can be narrowed to this sub expression:
DateValue(TextBox1.Value)

Thanks for your advice.
