Solve Block for 3 eq'ns 2 unknowns for vector inputs

$

I have some data that I am reading into a worksheet.  For each line of data, I would like to solve for 3 unknowns.  I have three equations so that should work.  I have checked the equations within the solve block by copying them outside the solve block to see if they work and they do as can be seen after the find statement.

 

I tried 'trace error' and it seems to give a nonsensical error.  Something about a squared term should be a function.

 

I also tried to make my vectors of length 1 and 'trace error' gives a different error.

 

I thought of trying to make the solve block a function but I am not sure how to get it to return 3 different values which don't have consistent units.

 

The worksheet and example data is attached.  I am using v14.0 M020.

 

I appreciate your suggestions.

 

Jake
