Javascript expert help us decode a script

We have several javascripts that have formulas, that rePrice some items and then create new html pages. There is a database which is a .js file. We need to extrapolate date from this. We already have found the visible items, but now there is a formula that basically reads mstr+='<a href=javascript:rePrice(' + [login to view URL] +',"' +this.thing+ '")>' + [login to view URL] + '</a> '; if ([login to view URL]('P')<0){ etc. etc. etc. then there are some files with arrays in them. We need to decipher the files and figure out what the formula is so we can build a database in excel out of the formulas being used. We do not need anything written, we just need you to tell us how they are compiling the data and what formulas are used and what they are based on.' DO NOT BID UNLESS YOU ARE AN EXPERT AT THIS. We can already guess ourselves what they might be doing, we need someone who can read the thing and KNOW what it is doing. We need this in a few hours.
