HELP: Need a jump start equation back solver

[BruceH]

Not quite sure what you mean by "I have 25 sites using different sized variables" but if you have more than 10 expressions and need more than the 10 rows of the Solver App then simply save a copy of it.

To do this press Apps, select Solver (but don't start it), and one of the menu options is Save. Press this and give it a new name "Solver2" for example.

Now you see Solver and Solver2 in your list of apps. Solver2 starts out as a copy of Solver but any changes you make are independent so you can have another 10 expressions.

Repeat once more to create Solver3 and you now have space for 30 expressions.
