I have a field that is auto-populated with an "X" when any one of 6 fields are changed. It works fine, but now I need it to pop up a message asking whether to print or not. The X field is set up in the field definition, so I don't know if this can be added to the calculation or a script has to be called.

Printing can't be part of a calculation, you will need a script. There is not direct way to trigger a script with the change of the result of a calculation. There is a plug-in that will trigger a script upon exit from a field.

I don't want it to call a print, I just want it to show a message when the field changes. The message will just ask, "Do you want to print?". The field that is populated with an "X" when it is changed is already in place and working. Is there any way for it to "Show Message" when that change takes place?

I hope this explains it a little better.

Thanks

You can create a calculated field like so:

PrintMsg = case(ChangeField="X","Would you like to print?","")

You can combine it with the hidden portal trick to display a print button when the changefield has an x in it.
