CSV export bug in one report

Question

Hey guys and Apex-friends!
I have a problem with the export of one of my reports.
The Column BF is always empty when exported to Excel. In fact, the header is created but the results are not shown.
If I drop the Page item P480_BIOTOPBAUMFLAECHE the data is exported as it should be but false of course. I just did that for testing purposes of course.
On my page the results are displayed correctly. I guess that the computation is not carried out. Is there a way to fix that bug?
Here is my report query!
select
:P480_BIOTOPBAUMFLAECHE as flaeche,
count(b.lng_baumart) * 10000 / :P480_BIOTOPBAUMFLAECHE AS bf,
LNG_BAUMART,
p.STR_LRT_MAIN
from
VT_TBL_BIOTOPBAUM b,
VT_PUNKTDATEN_JOIN p
where
(p.CNT_GEBIET = :P480_CNT_GEBIET)
and (b.LNG_INV_PT_ID = p.INV_PT_ID_SUB)
and (p.str_lrt_main = :P480_STR_LRT)
and (b.int_bezug = -1)
and (p.int_status_sub = 3)
group by
p.STR_LRT_MAIN,
lng_baumartIf you have an idea or hint, please let me know!
Thanks a lot!

Hi,
I do not know does this help, but try
select
:P480_BIOTOPBAUMFLAECHE as flaeche,
count(b.lng_baumart) * 10000 / TO_NUMBER(:P480_BIOTOPBAUMFLAECHE) AS bf,
LNG_BAUMART,
p.STR_LRT_MAIN
from
VT_TBL_BIOTOPBAUM b,
VT_PUNKTDATEN_JOIN p
where
(p.CNT_GEBIET = :P480_CNT_GEBIET)
and (b.LNG_INV_PT_ID = p.INV_PT_ID_SUB)
and (p.str_lrt_main = :P480_STR_LRT)
and (b.int_bezug = -1)
and (p.int_status_sub = 3)
group by
p.STR_LRT_MAIN,
lng_baumart
