assembly code bankselect problem

[ceibawx]

Dear Friend,

I compiled the code followed. It did pass simulation last Friday. But today, problem appeared.-------------------------------------------------------
Message[302] C:\DOCUMENTS AND SETTINGS\GRACEE\MY DOCUMENTS\PNS2\PNS2.ASM 62 : Register in operand not in bank 0. Ensure that bank bits are correct.
Message[302] C:\DOCUMENTS AND SETTINGS\GRACEE\MY DOCUMENTS\PNS2\PNS2.ASM 63 : Register in operand not in bank 0. Ensure that bank bits are correct.
Message[302] C:\DOCUMENTS AND SETTINGS\GRACEE\MY DOCUMENTS\PNS2\PNS2.ASM 64 : Register in operand not in bank 0. Ensure that bank bits are correct.
Message[302] C:\DOCUMENTS AND SETTINGS\GRACEE\MY DOCUMENTS\PNS2\PNS2.ASM 67 : Register in operand not in bank 0. Ensure that bank bits are correct.
Message[302] C:\DOCUMENTS AND SETTINGS\GRACEE\MY DOCUMENTS\PNS2\PNS2.ASM 71 : Register in operand not in bank 0. Ensure that bank bits are correct.
Error[113] C:\DOCUMENTS AND SETTINGS\GRACEE\MY DOCUMENTS\PNS2\PNS2.ASM 122 : Symbol not previously defined (LoopThree)
Halting build on first failure as requested.
I don't think that the error exists in my code. But the simulation said like this.
Can you help me to see the error in the code?

Bankselect there are two kinds of method. One is use "banksel", for example, "banksel TXSTA" means that code works into bank1. The other is use "bsf". "BSF STATUS,5" and "BCF STATUS,6" can shift into bank1. I didn't write wrong. why simulation didn't pass.

The second is "LoopThree". I think that no problem. why it is also not passed in simulation?

Bankselect there are two kinds of method. One is use "banksel", for example, "banksel TXSTA" means that code works into bank1. The other is use "bsf". "BSF STATUS,5" and "BCF STATUS,6" can shift into bank1. I didn't write wrong. why simulation didn't pass.

You will always get this message for any variable not in bank 0.
This message 302 was added to remind you to check your code, particularly code in banks other than 0.
You can use the errorlevel command to turn this messages off.

The second is "LoopThree". I think that no problem. why it is also not passed in simulation?

END
LoopThree:

To remove 'END' above the 'LoopThree'.
