Hi adam. I think that there is a misundestood here.  I do not copy from members area because: first = I DID THE CALCULATOR  second = im not a member yet. So, i only should post the link here. third = if someone post the calculator on member section , i think it was without my knowledge. 4th = YES i do read the rules of the forum and about copying threads from one area to another.  So, lets verify this ???  Thank you See you
