Password protection dosent recognise password

[shrek]

I have a workbook which when I click on from the folder it keeps asking me for a password. Ive tried to set it up so that it recognises the password but still no luck. Ive gone into the MVB and selected this workbook. Also Ive selected this workbook and open and input the following code.

Activeworkbook.Open Password:="trumpton"

I thought that would auto recognise the password and open the workbook but it dont. Anyone any idea's?
