In visual basic, when in the "frmMain Events: Load", I get the following error

The type initializer for 'projData.projDataModule' threw an exception.

when running the code:

var = 180

"var" is defined in projDataModule as

Module projDataModule
    Public var As Double
End Module

When I rebuild the solution, It says "0 errors, 0 warnings" and will actually compile, however the Error list shows the following error:

Error   1   Custom tool error: Failed to generate file: There is an error in XML document (1, 1).   I:\Documents and Settings\Bill\Desktop\Projects\Data\My Project\Application.myapp   1   1   Data

Any ideas or help at all would be greatly appreciated. Thanks in advance.
