Framemaker allows for expressions.
The issue is shown by the paper size expressions in the Media Size appendix for ISO and JIS B sizes. There are expressions with numerical values of 1.5 and square roots etc.
When build locally these work ok. The build server results in 1,5 - i.e. the european style for numerical values. This is probably a language issue on the build platform/framemaker.
If this can't be fixed bounce the issue back as I'll need to rework expressions not to have numerical constant values.
