Userform not running for charts

Hi,

I am attaching the excel on which i need help.
I want to insert charts in the Userform5 based on the combobox option on the same userform.

I have gone through many forums and have copied the formula and tried my level best to display the charts.

The problem:-
The charts are getting displayed properly when i run the userform directly from the code window.

But as soon as i run it from the worksheet "master" using command button "Reports" the charts dont get displayed properly.

Request you to please help.

Regards,

Udit
