Dan,
There is plenty of code on attributes to put this together.
Do you know the tag name & is it the same every time?
Is the block unique to the space you are in, i.e. only one occurrence?
Here is the pseudo code 1, tag name constant
- User selects the block
- Set default response string
- User option to edit response string
- Update the attribute
- Refresh the object
Here is the pseudo code 2, block unique, but tag name varies
- User selects the attribute, via nentsel
- Set default response string
- User option to edit response string
- Update the attribute
- Refresh the object
Here is the pseudo code 3, block unique & tag name constant
- Get Block, Verifying Tag
- Set default response string
- User option to edit response string
- Update the attribute
- Refresh the object
