Date Problem Between ActiveX Input Box And SQL Query

Hello All,
I am new to MS SQL Server 2000. I come from a Unix/Oracle/sqlplus environment. I am having problems in my where clause when comparing an ActiveX user input date to a date from the database. Or, I think that's what my problem stems from. I have a DTS package that pulls info from a table to an Excel speadsheet. I added an ActiveX input box under Workflow Properties to prompt the user for a date. I want to pass this date into the query on the where clause to pull only those rows where the updatedate = the input date. The DTS package executes just fine but it doesn't select any rows. Can someone tell me what I'm missing. I have tried inputting the date several different ways in combination with different convert/case in the where clause. Thanks in advance for any guidance......wisa64

My ActiveX script is:
Function Main()
dim tamdate
tamdate = inputbox("Enter Date")

Main = DTSStepScriptResult_ExecuteTask
End Function


My Query is:
select consumerid, servicedatefrom, updatedate
from tbl_cs_sv_service
where convert(char(10),updatedate,101) = ?

P.S. I have a Global Variable setup under Package Properties called tamdate of type string. And, I have a parameter setup under Transform Data Task Properties called tamdate.
