relationships problem

[Araz]

I'm trying to define a condition for a workflow in which if one of an accounts product fields gets a specific value then something should happen. I think I should create a relation between account and product. I've done that in both ways in both Accounts and Products vardef files. with lhs_module=Accounts and rhs_module=Products or lhs_module=Products and rhs_module=Accounts. the raltion is created in database when I rebuild it through Studio but it won't do no good.
I tried to create workflows with target module both Accounts and Products and when I try to define conditions I can't see Accounts or Products in the related modules.
Is this (creating relations) the only thing that should be done? is there anything I've done wrong? I have no idea what should I do

this relations problem is really getting on my nerves. The Problem is I can't create relations nowhere. although I think that I've added them to the vardefs crrectly cause sugarcrm gives me no error when I use the Admin tool to create them in DB and appropriate rows are added, but it has no effect in related modules when I'm trying to create a report or nowhere else.
