Dear all, In one of my form, I put a combobox which has 1 to 10 in the rowsource as predetermined selections. The combobox has a controlsource as a field in a table which is numerical type. The problem occurs when I assign the Control source to the combobox; it becomes disabled, (I can not pop down the menu for selection). After I remove the assignment to of the control source, the combobox returns to enabled=.T. How can I make the comboBox enabled so that the value I select would be written to the table? (I assume the situation occur for the data type from the pop-down list is not the same with that of the table field. One is character, and the other one is numerical.) Many thanks in advance. Regards, Ron
