Parameter substitution in DTS package

I have a DTS package containing two global variables, FromEmailAccount and ToEmailAccount.  (These variables are set at design time to normal looking email addresses.)  

The package also contains an Execute SQL task.  Here is the code for the task:

      declare @FromEMailAccount nvarchar(255)
      declare @ToEMailAccount  nvarchar(255)

      set  @FromEMailAccount = ? --Global Variable 'FromEMailAccount' assigned here
      set  @ToEMailAccount  = ? --Global Variable 'ToEMailAccount' assigned here

      update CheckValues
      set
            CheckValStr1 = @FromEMailAccount,
            CheckValStr2 = @ToEMailAccount



When I try to parse the query in the Execute SQL Task Properties dialog, I get a cryptic error message saying "Syntax error, permission violation or other non-specific error".  I get a similar error when I try to use the Parameters button.  

In order to assign the input parameters, I used disconnected edit and set the InputGlobalVariableNames property to "FromEMailAccount";"ToEMailAccount".    

Unfortunately, when the code runs only the first character of the global variables values is written into the CheckValStr1 and CheckValStr2 fields.  Why?

Does this work:

update CheckValues
      set
            CheckValStr1 = ?
            CheckValStr2 = ?

Are the global variables set the correct data types? You might want to use the Set Prpoerties task rather than a disconnected edit.

Lastly, this ~may~ help. It has some tricks you can use with parameters (when using SP's)

Unfortunately, I couldn't solve this issue.   The article was interesting (I had already read it) but none of the infomration helped.  I wound up removing all the substituted parameters as a workaround.  Simpler is better in this case.
