Error 1004 and 424 upon workbook open

By objects i mean VBA objects or controls e.g. combobox
by value i mean the value property of the object

so I have a combobox set up as a list box with a user specified value

before anything is selected it has value of ""
after something is selected the value changes

I don't have anything in the workbook open event

I dont have any sheet events either

the only event that is triggering is the ComboBox_Change event
and that is when i get the error

This only occurs when something was selected from the combobox list and the workbook saved
the error occurs upon re-opening


Thanks again

Here it is
