Hi Annie,

Origin 7.0 uses the same old technology of NLSF as in Origin 7.5, so, 7.5's method in general should likely work in 7.0. I don't know why it didn't work in your case.

If you can use Origin 8.0 SR6 somewhere, you can try the following tutorial:
  http://wiki.originlab.com/~originla/howto/index.php?title=Tutorial:Fitting_Datasets

Or, if you simply need to get the result just for now, you can download the latest evaluation version from:
  http://www.originlab.com/index.aspx?go=Downloads/OriginEvaluation

to try the above method in the tutorial.
