How do i fix those 302 messages?
* Also,
I assume the 306 message below can be safely ignored.
003A 1B86 00110 T4L: BTFSC PORTB,K1.4 ; Wave
enable input, 0 => enabled
003B 284C 00111 GOTO T5L ; skip lookup code
when disabled
003C 3009 00112 MOVLW High(tab4)
003D 008A 00113 MOVWF PCLATH ; may be in
a different 2K block
Message[306]: Crossing page boundary -- ensure page bits are set.
003E 21A9 00114 CALL tab4 ; far call
003F 07A8 00115 ADDWF amplo ; add lookup value
to amplitude
Help please?

Those troublesome PIC bank select bits are something you'll need to read up about the topic from the data sheets and/or application notes. From my vague memory of an old project of mine, bank control is used to tell the machine which bank from which to execute instructions and access RAM or registers. You'll need to plan the layout of your code and data in the various banks when your code and/or data grows beyond the limit of what bank 0 can hold.
