Ranks & Titles by custom profile field values?

[troybtj]

The website I am running is run by donations for a game.

I'd like to add to parts to the postbit_legacy area, based on fields, if it the built in rank/title can't be changed to look at a value other than postcount.

Here are the exact details:

For one parameter (custom field), it would be how much they have donated to the site, and would get dollar sign "stars" in their postbit based on the number in the custom field (which is edited by admin only)

Second parameter (custom field) would be the same thing, except with a different icon for amount of game participation and forum help they have given, along with adding an additional custom title. (again, edited by admin only). We all know postcount != forum help

Both of these fields would be a numeric value to calculate the rank, or "bracket" the title (1-100=blah, 101-500=argh, etc).

I guess the base question is if I use the above post for a template, is there a way I can eval the value (numerically) of the custom field to decide which icon to display?

I do not understand the functionality of "condition" on "If Condition=xxx" or how to evaluate/compare numercal fields in "proper vB"

All help would be appreciated! I am familiar with PHP, but don't want to make any changes that would hurt the upgrade process, so am looking for an official method first.
