Nested Subcircuits in Spice Scripting

[Ahmad Bassam Sayed Ayoub]

Please, I hope if anyone can help me with this error in this script.

I get this error:
Fatal error: b:mos:s: unknown controlling source mos:b1
doAnalyses: No such parameter on this device

I hope if anyone can help me.

Find below the circuit model script.
