FlexCelReport.EnterFormulas Property
When true, FlexCel will try to enter any string starting with "=" as a formula instead of text. If this property is true, any string you enter that starts with "=" must be a valid formula, or an error will be raised. When you know a priori which cells will have formulas, you might want to use the <#formula> tag instead.
