I have read multiple posting about the "Column does not exist" error and have not been able to figure mine out. It accepts some just fine and then does not accept others.

Sharepoint Columns

Every other column is selected but for some reason "Summary" along with a few others such as "TimeH" and "TimeM" will not be recognized. I have refreshed, restarted, deleted the data source and re-added and nothing seems to work. Please help.
Also when using the datepicker, what format is the coding? such as .text, .seleted.value, .value, .number?
