listview question

when i try and add some text and numbers into a listview control, the text works fine, but the numbers are not added.

mdx SetControlMDX $dname 3 ListView report rowselect grid single > $mircdirmdx\views.mdx
/did -i adminmodcalc 3 1 headerdims 125:1 125:2 125:3 125:4
/did -i adminmodcalc 3 1 headertext User $+ $chr(9) $+ Password $+ $chr(9) $+ Access $+ $chr(9) $+ Description
/did -a adminmodcalc 3 12345 $+ $chr(9) $+ password $+ $chr(9) $+ 131071 $+ $chr(9) $+ testing

would add nothing to column 1, password to column 2, nothing to column 3, and testing to column 4??
is it something wrong with my code or is it a bug with mdx?
