Databound controls showing no data

I have a strange problem with one of my wizards. The Wizard is bound to a table and is being opened in edit mode. I have no problem with the fields already on there, they are displaying the data from the DB fine, but for some reason any new controls I put on there are not showing the data, they are just blank. I've checked the control properties and they are identical to the controls that are working. I've even copied and pasted a control and the pasted control contains no data and the original control shows the data as it should. Any ideas what could be going on?

A bit strange. Go to the Extended data, open the databuilder and test again. Try the Wizard and if it's still broken right click on the wizard, show data table and look for Errors - that might give you a clue.
