VFP 5.0 is not accepting the following code:

IF NOT EXISTS(SELECT c.guro_id FROM (this.cursor_name) c ;
WHERE c.guro_id = EVAL(cur+'.guro_id'))

this.cursor_name is the name of one cursor and cur is the name of another. VFP gives me the compile error 'Function name is missing )'.
I do not see any missing parens, so something must be provoking the compiler to expect a close parens prematurely. BTW, my usage of EVAL and the parens around this.cursor_name are based on what has worked for me through trial and error.

Thanks in advance
