Are there any sharepoint 2007 gurus out there? I am in dire need of assistance creating a sharepoint 2007 approval workflow, I've rewritten thsi thing about 30 times in sharepoint desginer and I stillc an't get the hang of it

for example, is there a way to express greater than or less than in the conditions? all i can find is equal to and not equal to

how do you tell a Wf step to wait for somethign to happen?

- i can set a wf to wait until certain fields change, but how in the heck do I apply that field change, from the user end?

I have a lost of questions, could really really use a hand on this one. thanks.
