Invalid value for property '<property>'
You have entered an invalid value for a merge module configurable item. Configurable items are properties provided by the author of a merge module; the author specifies the required format.
Common errors include blank values, incorrect data types (for example, a string instead of a numeric value), or incorrectly formatted file names or paths.
If you are the author of the merge module, there may be a problem in the ModuleConfiguration table. For more information, see ModuleConfiguration Table.
To correct this error
Double-click the error in the Task List to go to the merge module in Solution Explorer.
In the Properties window, select the (MergeModuleProperties) property, and expand the node to see the configurable items.
Select the property referenced in the error message. The description at the bottom of the Properties window may provide information about the required format; or if the author has provided Help for the property, you can press F1 to display the Help page.
If no Help is provided, you may need to contact the author of the merge module for more information. The author can be determined by looking at the Author property for the merge module.
