Re: [Quickfix-developers] Simple beginner questions

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

I am able to extract the value, however I do not understand the logic 
behind it.

Additionally, I would require a few tries before I'm able to get the 
value. Is this a problem on the server side?

Thank you so much, Mr Chan
