#+TBLFM: @1$5=vsum($4*1.225);%.2f p20 f20::@2$5=vsum($4*1.225);%.2f p20 
f20::@3$5=vsum(@address@hidden);%.2f p20 f20

I am trying make the spreadsheet above with org-tbl. When running C-u C-c C-c I 
get this error-message:
"org-table-recalculate: Symbol's value as variable is void: org-table-modes"

When not using "p20 f20" the spreadsheet works fine, but I need the precision.

I'm lost on how to fix this issue or how to work around it. Hopefully someone 
can explain what can be done to make this work.
