akoj - the
members_resultsbit is a member search result page. The variable is not $post, it is $userinfo, so use $userinfo[itrader_total]...
The Wise One The phrase 'itrader_positive_feedback' is in the iTrader phrase group which probably isn't loaded. You can create one for whatever the member stuff is supposed to be on or in the GLOBAL group, or just don't use a phrase.

Also, you are trying to add the wrong variables, the variables are
itrader_total &
itrader_pcnt, not tradescore & tradepcnt.
Everything variable-wise should start with 'itrader_' so that it won't ever conflict with other products or variables.
