It depends on what is ItemNo.... How do you want to trigger it?

A general syntax would be like this

sub Message

if( len(ItemNo)=0) then

msgbox "You have items with No. Name"

end if

end sub

Hi Erich,

Thanks for Your Reply ..

Sorry I am not clear on my requirement in the above post .

I have a Graph.. User can see it by clicking on the button. But before clicking on the button the User should select the ItemNo. If the User Clicks on the button with out selecting the Item No. A Message should POP up that "Please select the Item No". If the User Selects the ItemNo and Clicks on the button the message should not display .

This is my requirement

Regards,

Alvin.

Ok!

You probably don't need a macro for that.

On the chart properties -> general tab. you can include a calculation condition like this:

=if( count(distinct ItemNo)=1,1,0)

Then, you include an error message to tell the user he should select something.

(on the same properties tab, click on error messages and include something at calculation condition unfulfilled)

Or you can include the same expression on the layout tab -> show conditional -> to hide the chart completely.

Hope it helps,

Erich
