Using an enum in an OQL dataset

I have tried using an enum as the source of a drop-down list in my OQL report. When I specify the parameter I get this error: 'The report cannot be generated because the user does not have sufficient rights to access parameter xxx'. I cannot see how to get past this - all entity access rights are in place, so it is not a role issue. It seems that simply creating the parameter causes this error. Any advice appreciated. David

The answer is . . . . Open the security page for the module and update the settings in the pop-up!
