drill through from a crosstab measure

[coolbaba]

Hi all,
I have a unique drill through report from a crosstab. I have person id in row and year (level-1) and month (level-2) as columns and amount as measure. i have created a drill through from the crosstab fact cell passing person id, year and month as parameters to the child report.when i click the hyperlink on the measure, I am able to pass person id and year but the month is not passing through. is there any issue with levels? I mean the no. of columns in levels added to a crosstab? Month is currently serving as level-2 under year. or is there anything i need to check before to use drill though from measure in a crosstab.

please help

Rgds,
S
