"Unknown operation" error from an "if" statement

Hello everybody, I have written a g code file comprised of subroutines designed to provide a quick and easy way of creating supports for a coil make of copper pipe on a CNC. I tried to load the file in LinuxCNC, and I received a message that said "Near line 70 of primary cutter.ngc: unknown operation." I think the error is being triggered by the "o110 if" code on line 69, because the code "o<turn> call" appears earlier in the file without causing any problems. Can somebody tell me if I have correctly identified the problem here, and if so, how I could fix it? I have looked at the LinuxCNC documentation page for o-codes and cannot find anything wrong with that line of code. The file is attached.

Thank you,
Cameron

(if we are cutting the first support, cut an extra notch for the nth turn)
	o110 if [#<_nsupport> eq 0]
		o<turn> call
		o<cut> call
	o110 endif

I don't see a o<support> call and it is the outer loop.
