Run Time Error-380 "Could not set the value property. Invalid property value"

[QUOTE=cijo] I am having problem with my same excel workbook.

While clicking Combo-box of "Filter by Month/Year" and then Click Combo-box of "Filter by Vessel" some values, list box gets populated. When I click listbox the value, I get Run Time Error-380 "Could not set the value property. Invalid property value"

Plz assist

Find attached my excel sheet which I am working on.

Follow below instructions for working on my userform:

a) On opening the workbook, a userform appears. Select username value as 'Others' and then press button 'Enter'

b) Other userform will appear. Click Combo-box of "Filter by Month/Year" value "October:2012". Then Click Combo-box of "Filter by Vessel" value "Jag Lalit. Then list-box will show some value. When I click the listbox I get the error.

d) Click Exit button to close the excel workbook.

To open code:

a) On opening the workbook, a userform appears. Click button 'Admin' and then type admin on the textbox that will appear then,and then press 'OK' button.

b) Workbook will be visible. Then you can go to code as usual.

Combobox4 isn't enabled when you get the error.

However setting it to enabled doesn't appear to solve the problem.

The only way I could find to stop the error was to replace the existing comboboxes with new ones.

I replaced the code UserForm1.ComboBox4.Value = Employee.Offset(0, -5).Value. The problem still persists.

Which all comboboxes should I replace? All of them in the workbook?
