Hi all.
I'm sort of new to the programming game. Boy what a learning curve.
I understand ladder logic better than basic. Anyway, I've got an idea to turn on 12 jfets, in order from 1 to 12. using a picaxe28X2 and out putting the jfet number to a 20x4 serial lcd.
Using the simulator, I've got the lcd screen to display what I want it to, and
the 28X2 outputs fire in order, but, I'm having problems getting the numbers to display correctly. At the moment the numbers start with 1 and continue to fill the screen with numbers 1 through 12.
Thank you

Welcome to the PICAXE forum.

Noting that you are using a baudrate of 9600, suggests you are using other than the Rev Ed AXE033.

Can you provide a link to the LCD display(s) you are using.

I presume that the values 1, 2, 3, 4 are being displayed each further to the right across the display and maybe eventually wrapping onto another line.

For now, guessing as to the control commands being as per most LCD displays:

with respect to your code, where you have lines such as:
HIGH C.5 serout A.0,N9600,(144," 2")​

it is likely that you need to indicate that the 144 is part of a control command to position the " 2" which is what you want displayed.

try changing them to
HIGH C.5 serout A.0,N9600,(254, 144," 2")​


EDIT:
the 254 is a control code that indicates the following value (eg 144) is an action to be performed.
