[ADS] ADS netlist error

netlist error above appearing on my Momentum simulation. Please let me know how to solve it. thanks.

Show me line 54.

sorry, solved the problem myself. the goal which i set to optimize impedance looking into port 1 is wrong. i set wrong experssion in the goal. i set complex impedance at 1st which is the mistake. when i separate the impedance into real and imaginary, the issue solved. thanks anyway. :)
