Qualifier must be collection
- You used a name on the left side of the exclamation point (!) that isn't the name of a collection. If the name is supposed to represent a collection, check to make sure the name is spelled correctly. Note that the exclamation point is also thetype-declaration character for the Single data type. If the name in question isn't supposed to be a collection, perhaps the ! type-declaration character appended to avariable name has been concatenated with another name.
