Thanks for Reply Mr. Peltier,

I have moved code to the regular module.
Problem did not fix.

The combo box should be assigned to a procedure in a regular code module,
unless you have defined a class module to capture ComboBox events, in which
case you need to instantiate the combo box as an instance of the class when
the workbook opens.

Hello,

I have a combo box on my chart.
I have writtten a (Sub) procedure in a class module.
ComboBox calls the Sub A.
Works Accurately, but when I reopen my file, code does not run by ComboBox
and I have to re-assign Sub A to the combo box.

How can I resolve this??
