Unsupported feature error

Hi, I am coding in verilog at switch level. During compilation, my software keeps giving me the following error message.

Error (10015): Verilog HDL unsupported feature error at file "DorQ.v" (line 14): can't synthesize tran, rtran, or tranif bidirectional pass gate primitive

What is the problem, shouldn't Quartus be able to synthesize bidirectional pass gate primitives?

Please help.

    No. Modern fpgas have no internal bidirectional components. If you're trying to write code at the primitive level, I suggest you read the reference manual for the device you are using to see what parts there are.
