ssis 2005 passing variable to ToLine

I am able to read an oracle table.
I can pass the result set to a for loop .
I can select each column in the for loop and diplay it in a script
dts.variables("strEmail").Value.ToString.

My sad state or despair:
After my script to display a message box, I have a send email control flow it works just fine if I hard code the ToLine.  
I can also use the message type and message source to pass in a variable for the message body.  NO PROBLEM, the emails work with ToLine hard coded.  
Here is the issue.  I want to be able to send (reminder) emails to a variable number of users (changes month to month) in the ToLine of the Send Email task in ssis 2005.  This will not work so far.  It seems the ToLine does not except a variable.  

My variable is User::strEmail.  Please note this variable does have the email address because if I use it in the body of the message and hard code the ToLine it works!!  I can see the email passed in as a vaiable in the BODY of the message for multiple messages sent to the same HARD CODED ToLine address.  I want to set the ToLine to this value.

I have tried in my ssis control flow send email task ToLine:
dts.variables("strEmail").Value.ToString
@[dts.variables("strEmail").Value.ToString]
User::strEmail
strEmail
@[User::strEmail]

I tried setting the Expression (in ssis Send Email Task) ToLine to dts.variables("strEmail").Value.ToString or User::strEmail. Using the expressions opton to set ToLine to a variable will not except it says evaluate to null.  

Is it possible to set ToLine in the Send Email task to a passed in variable?  Has any one got it to work? And naturally I may be doing something stupid, so forgive me if I am.

You can do this, you just need to use an Expression to define the ToLine value. See picture below.

I have done this.
I have set ToLine drop down list select to
@[User::strEmail] selected from variables, typing.
The User::streMail works fine in the body of the email.

This is the error message when I try to run the job:
Error at Send Mail Task [Send Mail Task]: No recipient is specified.

Ahh, no value in the variable?  Put in a script task that includes a msgbox. Display the value fo the variable before the sendmail task.

I did that before I posted the message.
Sorry, but I am able to easily put the variable in the body of the email as a passed in variable.  I cannot get it to accept it as a ToLine variable, no idea why?  So yes I can my send email with a script message box displaying the variable.  I can send emails with the variale in the body of the message as I stated from the start.  I just cannot get it to be accepted as a ToLine variable.

I am sorry if I am missing this, but are you using the Expressions tab to set the ToLine property? Not typing the variable into the ToLine field on the Mail tab.

I absolutely used the expression tab to set the ToLine property. Does the variable run for you in the ToLine if you execute the code?

Yes. If the variable is the Expression, the Expression will evaluate when the SendMail task is executed. If the expressions returns a value then it will be in the ToLine - everytime.

I apologize for this long delay.  I was pulled off on another project and had not had a chance to debug further.
