Help with asm file and compiling

[tasmod]

Don't know where to go for help with this as it's and old project. It's also assembler so not really meant to be here as well.

I have a asm file of a frequency counter with offsets for amateur radio use. I also have a hex file that works on a single line 16x1 display.

Now I need another counter making I only have a two line 16x2 display. I understand that the code has the option for two lines and I tried to alter it by removing the 'single line' define which I assumed it would then use the 'if, then, else' to move to two lines.

However it won't compile because of two errors. This puzzles me as it says symbol not defined, however I can find the symbol in the code!

I've attached the codes but with added .txt at end as forum won't allow upload of asm.
