I would like to be able to have a text box to display multiple values from a drop down list box.  Is there a way to select from a drop down --> have that populate a text box --> clear the value of the drop down --> select another drop down value --> concat the new value with the previous selection?  This is for an injury/illness type report and there could be many selections.  I do not want to have to setup a bunch of check boxes like it is now.  That takes up too much space on the page and I will also have to add a lot of data sources to make this happen.

Thanks,
Eric

Have you tried the multiple selection list box control?  It only requires a single repeating node for your data source.  If space on the form is an issue, you can also make the control smaller and use scroll bars instead of displaying all the options. I would say this is definitely the easiest approach to handling multiple values.

If you still prefer your approach, you could probably accomplish this using a few rules.  You would need a dropdown field and then another field to store your concat string.  Create a rule when the value for the dropdown changes to concat that value with your concat string and store it in the concat string field.  Then just clear the dropdown and you're ready for the next value.  This solution won't prevent users from entering the same value twice though.  That would require some more logic to build in.  Hopefully this gives you a good start!

If you're using 2010, it will be in the controls gallery for browser forms.

 I ended up using "DelimitedList" inside of qRules along with a repeating dropdown list box, and a text box to accept the delimited value.  This will get me by and does what I need it to do until we finally upgrade to 2010.  Ended up with 8 different sections that fire the qRules control.  Thanks for all of the help on this.
