Hi,
I'm having an issue about putting a presentation variable in a column formula. I'm using obiee 11.1.1.7.141014
I'm adding a text in a formula column where I use two presentation variables: pPeriodo and pAno
pPeriodo invoques the month selected in a prompt and pAno the year. I have to compare different years, so in one member I use @{pAno} when is the selected year and @{pAno-1} when is the prior year.

The result of this (please see the header of the 2nd column):

The problem is when Icompare to next years. So my issue happens when I do an addition to the presentation variable: @{pAno+1}
It doesn't do the sum; it concatenates the value as you can see in the following images


If anyone have a workaround about this, please share.
Regards,
Miguel
