Displaying multi-line field values in ZML

Displaying multi-line field values in ZML

I'm sure this is obvious, but I can't find the solution...

I have a Form which has a multi-line field called 'Description'.

I can capture the field values using:

        // Get idea
ideaDetails = Idea[IdeaID == input.ideaID.toLong()];
// Define fields
ideaID = ideaDetails.IdeaID;
ideaTitle = ideaDetails.Idea;
ideaTestField = ideaDetails.TestField;
ideaDescription = ideaDetails.Description;
ideaProduct_Area = ideaDetails.Product_Area;

I can display values like ideaTitle without issue:

<text size='14px' type='Text' renderAsHtml='true'  value='<%=ideaTitle%>'></text>

But when I add <%=ideaDescription%>, or use any multi-line field, my ZML fails with the following error:

Error details:
Error in ZML snippet - zml_snippet1 in the page View Idea"
Line Number : 9
 Invalid content was found starting with element 'text'. No child element is expected at this point.

I also tried with renderAsHtml='true' 

<text size='14px' type='Text' renderAsHtml='true'  value='<%=ideaDescription%>'></text>

Any assistance will be tremendously appreciated!
