Hello

I want to fill up a form I download on internet. It is a document with the extension {FORMTEXT} written where I have to put information. The problem is that I cant manage to write anywhere. In the help it tells me that the button of the lock under the forms tool bar has to be LUCKED for me to be able to modify. Is it normal ? It would seem more logic if it the button had to be unlock. In any case if it is locked I can't written anything and to unlock it askes me a password that I don't have. What can I do ?

Thanks for reading !
