The records will not sort on my form. A combo box containing field names is used to change the record order. The "On Click" event of the combo box changes the "Order By" property of the form. The record order does not change even after a requery or recalc. What else needs to occur?

Right-click the combo box, then properties, then ALL, then RowSource then click the build button. You can specify the sort order there. I hope this is what you wanted...If not sorry to waste your time.. :)

Are you setting orderbyon = true
