type mismatch error when writing date to page

In version 6.1 build 2450 I attempt to add a code snippet to any page with the following code:
Response.Write "Date: " + Now()
And it produces this error in IE:
Microsoft VBScript runtime error '800a000d'

Type mismatch: '[string: "Date:"]'

/TheTool/include/jobs_events.asp, line 178
Am I doing something wrong?

Thanks,

Tim
