Problems numbering a mailmerge doc with condtional (IF statement)paragraphs

I am having more than a headache while attempting to autonumber my
paragraphs in a Mergedoc. My document contains conditional paragraphs
that are within IF statements. e.g. 24) blah blah blah {IF {MERGEFIELD
asdf} = "True" " 25) blah blah blah" "" 26) blah blah blah. What I
need to do is automatically renumber paragraphs based on the
conditional paragraphs. My document is 26 pages (not including
mergecode) and contains 50+ numbered paragraphs (sections) many of
which are conditional. This makes renumbering the entire document
every time I have a conditional paragraph undesirable. I have tried
the {SEQ} method of numbering (which doesn't like IF statements) as
well as normal autonumbering. Nothing has worked for me. Please help,
I am running out of aspirin.

Thx

My Document is laid out as such:

1) unconditional
2) unconditional
3) conditional
4) unconditional
5) conditional
6) conditional
7) unconditional...and so on
