Choice 1 of Box A populates Box B, Choice 2 of Box A allows user to type value

Question

Hi,I am trying to have a Box (Box B) populate based on the choices from Box A.  But it would be a combination of an autopopulated value or a value that the user types in (not sure if that is possible). Box A has two choices "Average Market Value" & "Purchase Price" that the user chooses If the user chooses Average Market Value in Box A--Other fields visibly appear and are user-populated (SourceName1, Val1Amt, SourceName2, Val2Amt, & avgVal)--Box B is ultimately auto-populated based on one of these fields ("avgVal")But, if user chooses Purchase Price in Box A, --Fields are hidden (SourceName1, Val1Amt, SourceName2, Val2Amt, & avgVal)--User can type a value into Box B  Is this possible or should I separate Box B into different fields? Thank you for any ideas on this one!Leslie

This is possible to implement with a script. So the form will work as long as the viewer the used to display the PDF supports field scripts, which means the desktop Acrobat/Reader.

I'm assuming that by "box" you mean a dropdown selection list. This functionality is requested frequently and you'll find lots of info on this forum. Search on dependent dropdown.

You'll also find info and examples here:
