What are "variable constants?" And what does it mean to
"[embed]...Solver within the Excel Solver code?"

It seems you want to fit a linear function to some data. If so, look
up XL help for the LINEST function.

I have an equation I am attempting to fit to some data via 2 variable
constants. However, my equation can't be solved directly. I CAN solve
this equation for my data result variable, but I have to use goalseek
or solver. I want to perform a minimization of a sum of the square of
the differences of my data values and my data result variable. To do
this I would need to imbed a goalseek or solver within the Excel Solver
code. Can anyone help me?
