Solve Block for 3 equations

[felder]

Hello,

I am having trouble getting a solve block to solve a set of three equations. Error message is nondescript and I am not getting anywhere getting it to solve. Any help appreciated.

Use the trace error feature to get more information,

Probably there should be a multiplication dot here.

P.S.: You really like it that every variable name is underlined?

This did solve thank you.

I am noticing that I can get many possible solutions by changing the guess values. If I take the values found and plug them back into the collapse pressure equation I am getting a value lower than the value I specified. Is there a way to get the solver to output values that will make my Pa=P`?
