Enforcing minimum period in wizard

Hi all,

In workbook wizard , there is an option to restrict user to select maximum positions in the workbook but no option for minimum positions.

I need to check if user has selected certain number of days from RPAS_TODAY onwards and show an error message when running custom menu if not. I tried adding a condition measure and compare the current keyword index but it did not work.

Rules look likes this.

1.  ConditionMeasureB=if( current >= IndexMeasure ,true,false)

2.  ScalarConditionMeasureB=ConditionMeasureB

3. ErrorMessage=if(!ConditionMeasureB,"error",ignore)

Thanks

Nick
