Classic ASP / MSSQL 2008 conditional check on bit data type throws error when false

Dear all,
I have recently run into an issue which I hope you'll be able to help me with. Our company is upgrading from SQL server 7 to SQL Server 2008. We have a classic asp application which compares a bit field in the database and displays content 
based on the condition. Here is an excerpt.

comp_exactAddress = allData(3,rowCounter) //get the bit datafield

if comp_exactAddress then

     //do something

else
     // do something else


THe issue is that when the bit field in the database is true (or 1), the content is displayed, but when the bit filed in the database is false(or 0), classic ASP is throwing an error saying 

Microsoft VBScript runtime error '800a000d'
Type mismatch: 'comp_exactAddress'


Could any of you help me please?
Thanks,
