Condition based on 3 attributes

Hi All

Calculations is not one of my strong points and am hoping someone out there can help with this issue:

Scenario:

In Request, I have a collection call "col" with two boolean values (Boo1 and Boo2) and a user field (user).

I need a condition that returns true.  So far I have:

Value = 'False"

Var=Request.col.Latest()

if var.boo1.ToText() == 'True' and var.boo2.ToText() == 'True' and var.user.Title != null: Value = 'true'

Return 'True'

However when running this I get the dredded error in XML Document(1,1).

Help please! (at least I've had a go!)

Thanks in advance.
