Using Excel file with DDT driver in code

Hi,

This is my first Testcomplete script and I want to access to Excel file using DDT but I got this error message: " An Attempt to work with Closed Driver"

I verified my Excel, it is 32 bits and as what I said this my first connection.

This is my code:

In this script, I need to loop the sheet1 of the Excel file and verify if the value of the column "STP_Name" is different to "name1" and the value of the "Execute" column is "Y", if it is the case, display a message "Yeeeees".

Any help please, how can I solve this error ?

Sub execute()
set xlDriver = DDT.ExcelDriver("C:\Script-Resources\BatchRun\filename.xls","Sheet1",true)
xlDriver.First
Value1=xlDriver.Value("Execute")
Value2=xlDriver.Value("STP_NAME")
Value1=xlDriver.ColumnName(ColumnIndex)
Value2=xlDriver.ColumnName(ColumnIndex)
while not xlDriver.EOF
if value2 <> "name1" then
if Value1 = "Y" then 
BuiltIn.ShowMessage("Yeeeeeees")
else
BuiltIn.ShowMessage("Noooooooo")
end if
else 
BuiltIn.ShowMessage("Environment file")
end if
xlDriver.Next
wend
end sub
Sub Test1()
Call execute()
End sub
