question marks for outputs of calculations

New to this Mathcad Prime here. Version 10.0. 

 

I converted a sheet from Mathcad 15, In the converted sheet, every time I change the inputs I get question marks on the outputs and have to go back and manually type the uints over again.

 

Is this a bug or can I solve this somehow. Thanks.

The Prime analog of M15 Math Styles are Math Labels.  I think the Xmas converter is being conservative with how it translates Styles into Labels, and is converting them to Variable Label, instead (Note the difference in colour between the units with a question mark and those without).

 

Try Calculating the whole worksheet. See if that makes any difference.

Oh, forgot to mention.

 

Mathcad Prime units are dynamic, not static, which means they are evaluated during calculation not when written.   The Mathcad 15 static unit checking was removed.

 

It’s well worth reading the Prime migration guide and Help to get a feel for how Prime units operate.
