I'm using FME Desktop 2014 sp2. I want to reproject the X,Y coordinates of a point feature type (mapinfo, in NAD83) into the appropriate NAD83 MTM projection. I have an attribute named "ZONE_MTM" (string) that gives me the MTM zone a need to reproject in. However, when I use the "AttributeReprojector" transformer and, inside it, use a conditional value, I systematically get an "invalid test expression"!

I have tried forcing a "string" or a "number" comparison (instead of the "automatic" comparison). I have also tried using "begins with" but I still get the error. Any idea why?

Here is the error log:

AttributeReprojector: Invalid Test Expression: TEST<at>Value<openparen>ZONE_MTM<closeparen>=7.
