Farzan,
That wouldn't work the way it was expected, as it still uses single quotes around the string. Chris's solution would solve that. Else John should use DOUBLE quotes around the string in the VALUE attribute. Something like this...
Code:
Response.write "<INPUT TYPE=""HIDDEN"" NAME=""criteria"" VALUE= """ & strCriteria & """>"
Hope that helps.
Cheers!
