Populate multiple items to a text field from a dropdown list

[critski]

I am trying to create a dropdown list that when I select an item from the list it adds the item into a text box but doesn't delete the previous text box item.  I am just struggling with how to get the text field to concatenate and not simply replace the existing data with the new.  I thought it might be something I could do with action builder but it doesn't seem possible with out additional scripting.

Try this code on the exit event of your dropdown list:

tfList.rawValue = tfList.rawValue + " " + this.rawValue;

I'm presuming that the list you're adding items to is called tflist. If it doesn't work, let us know.

Thanks that worked!  But how do I suppress it from displaying Null as the first response?

[jasotastic81]

if (tfList.isNull) tfList.rawValue = this.rawValue;

else tfList.rawValue = tfList.rawValue + " " + this.rawValue;
