No Solution Found

I'm new to Mathcad so hopping this is just a setup problem.

I have set up an equation to solve for t with known variables, one of which is exponent n.  Now i need to rearrange the equation to solve for n.  Please see attached.

I don't understand why I'm getting No solution found.  I am able to solve this by hand and also using a free on-line math web page i get the same solution. 

 

Help is appreciated.

In fact you don't need all those definitions. An (otherwise) empty sheet with just the last expression will do.

 

Success!

Yes, I see the problem now.  I only defined those variables to test the original equation solving for t.  I didn't realize that would mess up the solution for n.  

 

thanks for pointing that out.
