This is doing my head in...
I am working in Smath at the moment and find that one of my equations won't solve, says something about incompatible units...
Thing is, the problem element of the process is dimensionless... I checked this with my calculator, I can get an answer...
while i was trying to work out how to ask everyone for assistance I discovered the "Live" section of the site., I uploaded my file, bingo, it loads and all of the equations have solutions...!
Quick, download it..! When it comes back into my machine it won't solve again....
there's something wrong in the plumbing, but I don't know what it is, is there anyway of someone having a look at it with me....?

cheers,

Stu.

Well, Love me tender and call me Elvis.....
I got it... Smath doesn't work back up the page...
one of my formulas was essentially out of order and therefore couldn't calculate before it had values for all of the variables.....
