VHDL syntax problem? Xilinx problem?

[jesse lackey]

I'm using xilinx ISE 9.1.
On the below, I get:

ERROR:HDLParsers:164 - "F:/dev/len/4chan/vhdl_learning/try1.vhd" Line
243. parse error, unexpected IDENTIFIER, expecting COMMA or CLOSEPAR

on the line:
" if (which samp_out = 4) then "

and I'm at my wit's end. I'm new to VHDL so it is probably something
I'm doing. But I've spent an hour doing creative commenting-out (this
is part of a larger process) and getting nowhere and now it is a
showstopper.

my apologies for the poor formatting.
any advice greatly appreciated.

Thanks in advance.
Jesse

Ohhhhhhhh. sigh. (makes gun shape with hand, points to head, bang.)
thank you.
