Hello, I'm having a problem trying to increment an integer here is the code: <dtml-in "sqlView.expressCampaigns()"> <dtml-call "REQUEST.set('ctn', CTN + 1)"> </dtml-in> I have a SQL Query that returns a column called "CTN" in the database (MySQL) this is defined as an integer, and currently has the value of "20000" (the table only contains one entry right now). I want to set the variable "ctn" to the CTN returned from the query plus 1. This is the error I get: Error Type: TypeError Error Value: illegal argument type for built-in operation When I view the source of the page I just see CTN: 20000, which I had printing out at one point but have since removed, but no error information or anything. Any thoughts would be appreciated. Thanks, --James
