Dear Experts

On form1 I have pagefrmae1. On keypress event of Form1 I have following codes

If lastkey()=27 and thisform.pageframe1.visible=.t. && first condition
thisform.pageframe1.visible=.f.
endif

If lastkey()=27 and thisform.pageframe1.visible=.f. && second condition
release thisform
endif

In first condition, if I press ESC while thisform.pageframe1.visible=.t.
then form releases instead of thisform.pageframe1.visible=.f.

I want when I press ESC key it check the visibility of pageframe1.
If pageframe1 is visible then pageframe1 must be visible=.f.
Otherwise Form1 should release.

Please help
