G52 used in a loop Fanuc 16

I think I have a syntax error trying to loop a program. It is turning and milling on a 5" diameter bar, it doesn't pull the bar so I want to get 3 or 5 parts parted off per program run. Hoping to use G52 to update the work offset by computing the stepover per iteration.
Fanuc 16TB, program goes something like this:

Code:

:1005 (BACKPLATE TURRET1 PROG)
G0 G20 G40 G80 G96 G99
#1 = 0.0 (loop count)
#2 = 3.0 (Max iterations)
#3 = 0.262 (stepover CONST)
WHILE[#2 GT #1] DO1
#1 = #1 + 1

.
.
.

G52 Z - #3*#1 (Z zero update) <--- likely problem syntax
END1
G52 Z0.0
M5
M9

G0 G28 U0.
G0 G28 W0.
M46 (C AXIS JOINT RELEASE)
G54

M30

Error message was 004 variable/reference not found or something similar to that.

Try using common variables instead of system variables:
#501
#502
#503
Always use brackets, not parenthesis. Parenthesis are for comments.
And, why not use G54/55/56 instead of G52?
