formName.Show is not working
 

HI there,
I have a very strange problem today. My macro worked fine
before. But, I get
"Run-time error '438'"
"Object does't support this property or method"
which is to show the forms.
For example, I have a form named frmName, I use
frmName.show funtion to call this form, but for some
reason, this .show function is not working today?
Does anyone have any idea what is wrong in my Excel or
PC.

Thanks

Lee
