Timer error when verifying with RS Logix 500 1

[drkildow]

I haven't wrote any programs in a long time and kinda forgot alot. Anyways, when I try to use a TOF timer in RS Logix 500,and then verify the program, I get an error that states "Operand can't be a constant!". What am I doing wrong or not doing to get this error? PLEASE HELP !!

When entering the timer number, you must enter it in the form Tx:yy e.g. T4:1. This is due to the file structure of AB SLC processors.
