HFR Urgent Queris : Small thing...but not working...........

Question

Hi All,
I'm facing small prob. but i became big one.
Prob. 1) : in column A i have year dim with prompt.
in column b i need previous year of col A.
For this , in col b i used relative function with same as col a - 1.
but its not working.
Prob 2) : I have 2 grids. in col a,b i pull the data from same grid and col c,d i need to create a formula var of grid2
col a,b.
For this, i used the formula like this var(grid1.col[a],grid2.col[a]).but when i run the report it shows #error. Any idea.
Plz give me any solution for these probs......
Thanks

Answer 1

For Prob 1: Instead of using prompt for year, you can use POV selection for year, so remove the prompt, and make it current user POV for year for column A. For column B make it Relative member of Current POV for year with offset -1.
or you can put prompts on both column A and column B,, so the user will have to select two years manually, and this gives the user the chance of using any year he wants for column B instead of using always selected year -1.
For Prob 2: Since you want to calculate var of the 2 columns of 2 different grids, I am assuming that the rows of the both grids are exactly same. So, If you can add another column to Grid1 and make it same with column A of grid 2, then use it with your calculation. If you want you can hide it.
hope this helps
