Hello,

I filled

IB_Combobox.items with customer names

and

IB_Combobox.itemValues with their customer numbers.

IB_ComboBox.style:=csDropDownList;
IB_ComboBox.dataSource:=IB_DataSourceTableXY;
IB_ComboBox.ParamName:=CustomerNumber;

IB_DataSourceTableXY.dataSet:=IB_Query;

IB_Query.SQL : select * from tableXY where CustomerNumber=:CustomerNumber;
IB_Query.open;

With this configuration I can't set the Param 'CustomerNumber' and I receive
an empty Query.

What's wrong?
