unexpected result when using the condition interface tool

[MartWClimber]

Goodday,

I'm trying to get used to the condition interface tool for creating macro's.

but I'm running into a problem.

i've created a simple workflow where you can disable a container (container 7) see via a macro see Macro screenshot.

but this always need to be overwritten when a specific user is using this macro.

I know that the getEnvironmentVariable ("Username") works because I've tested this in a formula tool and the output was as I expected.

in the workflow screenshot for the S output (sum output) when I run this workflow in designer there should be no output present (because the box is check)

meaning that that container 7 in the macro should be disabled.

Is there a configuration I didn't set for the condition toolor the action tool?

NOTE: if I remove the condition interface tool the macro works as intended. when checkbox is check no output is generated.
