Another date handling issue

In a workflow, I'm creating a query string that selects for a project name and inspection date. If I remove the date portion, the query works. With the date portion included, I get an invalid query error.

This is what the date portion looks like: "InspDate = '" + string.Format("{0}", item) + "'"

In other workflows, I've had to add “CDate” or “date” before the date variable depending on use. Neither of those seem to work in this case.

I'm completely stuck. Any help is appreciated.

Thanks.
