Tab Leads in TOC-Stuck

Question

Hi,
I am really stuck with the tab leads in my TOC. The problem is that I have changed the layout of my TOC from normal 1 column (full page), to two column. And everything else is working fine, but I am not able to get the tab leaders in my TOC.
I tried tweaking with my reference page - it didnt work.
I tried tweaking with the paragraph designer for all building blocks...but nothing is working.
Below is my reference page for TOC building blocks...Please help.
Please help me identify this issue. Its really urgent.
Thanks in advance. (This is FM 8)

Answer 1

Ok, I actually changed the tab stops to something really small (0.3"), and also checked all the reference page settings.
I am not sure why this is happening. When I revert back to single column layout, it works fine, but when I use double column the leaders disappear.
Any idea how much tab stops should I try with.
Thanks.
