Pass Multiple Prompt Values Dynamically in a Publication

Hello

I have a dynamic list for list for my Publications of a Web Intelligence Document. The dynamic list has the following columns names

ID

Name

Email

Zone

and the Web Intelligence document has the columns:

Zone

Sales Value

I can't use Profiles because some of the recipients in the dynamic list do not have a BOE account

Lets say I use the following values

ID = 1   

Name = Sally 

Email = Sally@mytown.com

Zone = USA

This works fine and if I change the value of the Zone to another single value, (maybe Sally has been reallocated to a different Sales Region) for example:

ID = 1   

Name = Sally 

Email = Sally@mytown.com

Zone = UK

then this also works fine and the output from the Publication shows the correct value.

However, when I try and do the following, I run into problems:

ID = 1   

Name = Sally 

Email = Sally@mytown.com

Zone = USA;UK

The resultant output is blank!!! The prompt that is in my document that I want to burst is set to optional. I've tried using:

semicolons: for example USA;UK

commas: for example USA,UK

brackets and semicolons: for example (USA;UK)

brackets and commas: for example (USA,UK)

but nothing works and the resultant output is empty

Also, passing in a blank value for the optional prompt to return everything but this does not work either and the resultant output is empty.

I can't believe that this is not possible and would welcome any suggestions.

Thanks in advance.
