New Post: SPServices.SPFilterDropdown Error

Marc,

I changed the CAMLQuery and replaced the 'show in dropdown' with 'Show%5Fx0020%5Fin%5Fx0020%5FDropdown%5Fx00' and then tried "Show_x0020_in_x0020_Dropdown" as you recommended but I am still receiving the same error message each time.

Error in function
SPServices.SPFilterDropdown
Parameter
relationshipListColumn: Title
Message
Not found in relationshipList Operational Period
Click to continue""

Is there a hidden ID for a site column besides clicking edit in site settings and coping the name at the top?
