Well the most obvious thing is your calling a sub that doesn't exist.
Second would be better if you showed all your code as it's not obvious where the snippet shown fits.
Just sayin'.

According to the data sheet most instructions take 3 cycles except "Clear display" which takes 165. Suggest you explicitly declare the defines related to LCD operation and specifically LCD_COMMANDUS and LCD_DATAUS. Play with these values till Proteus is happy or turn off the warning if it works in your real world config.
