Text Fields and Pick Lists

First off let me state that I am loving this app and the potential use I can get out of it. There is a slight learning curve but that’s normal for all new things. With that being said, there are some functions that I am not sure how they are supposed to work. Text fields being the main one. By following the tutorial I was under the impression that I would be able to enter text manually into a designated text field. When clicking on a form that has a text field I get the box that says Enter a Value. However I cannot enter any values. I then must click on the button below it that says pick list and it gives me a list of pre-created or manually created lists that I must choose from or create a new one. Is this normal? Am I not able to just type in the text into a text field without creating a picklist with the data I wanted to enter into the text field? or am I doing this totally wrong and should be using another field to manually enter text.Also I cannot get the server features or dropbox feature to work. Pressing the power button in the left corner results in nothing happening. So is there something wrong with my phone? or am I just not using the program right?
