Question

• Set WEEK = 20
• Set LASTWEEK = 19

   * Set LASTWEEK = %CALC{$EVAL(%WEEK% - 1)}%

Week 20

%INCLUDE{PlanForWeek%WEEK%}%

Warning: Can't find topic Support.PlanForWeek20

Last Week (Week $LASTWEEK)

%INCLUDE{PlanForWeek%LASTWEEK%}%

Warning: Can't find topic Support.PlanForWeekCALC{EVAL(20-1)}

Why does the above try to include a page called PlanForWeekEVAL 20 -1 instead of PlanForWeek19?

Answer

If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

There seems to be an evaluation nesting limitation, apparently a INCLUDE << SET_PREF << CALC << SET_PREF does not work

Last Week using INCLUDE << CALC << SET_PREF :

%INCLUDE{PlanForWeek%CALC{$EVAL(%WEEK% - 1)}%}%

Warning: Can't find topic Support.PlanForWeek19

This example shows that a INCLUDE << CALC << SET_PREF does work, as expected.

As a workaround you can try to use CALC{$SET()} and $GET() instead of preferences variables.

Thanks Peter.

My goodness, this is unintuitive. I don't suppose there an engineering focus to simplify this?

File an enhancement request, ideally with a patch
