Is it possible to add a script to a form that when someone want to choose somthing he doesnt allow to do it there will be an Alert Massage ?

Like "Cant choose this option" ?

Sure a message box or expression box can be triggered in a rule action.

So have a rule that the condition is that this user can't click this bottun or change this field.

Set the action to message and enter the text.

Then check the stop processing rules check box. That way the rest of the button function won't work if that case is true.

Also check validations that might be what you are looking for.

Open the property dialog for the textbox. Click on data validation button. this will open up a dialog to you. click add button from it. this will allow you to add validation for that text box. specify the condition for validating the user entry and in the "Message" below the screen tip you can specify the message that you want to popup to the user when the validation fails.
