Project Step, setting macro value for "Continue Building" corrupts project

[jaylab]

I have a build project in which I have created a global macro that I use as a flag to determine whether the build is for INT or Development use. If it is being used for INT, I log any build errors and move to the next component, continuing the build. If it is Development I want it to stop on failure.

When I set the "Continue Building" checkbox to use the macro the project corrupts. When I close and re-open the project it gives me a "Type Mismatch" error and will not open.

This works fine when I do not use a macro value.

Is there anything I am doing wrong?
