Fixing position of Userform

Hi,
In the attached excel sheet, i had got it solved by royUK.
All i want to know is that.
If i want Cell C1 to keep blinking to draw users attention when excel is opened, what do i need to do.

Secondly the User form (Key)always appears the centre of the page. If i want this to be always fixed between rows 1 and 3 soemwhere near D2 to H2. How can i make it fixed in its location
Thnks
