Tian,
Error #11 is "invalid function, argument..." and I can't find an error as "Illegal access". If the first is correct, you probably using forms() collection parameters wrongly (ie: _screen.forms(1).name is chartype where _screen.forms(1).left is numeric). You would need something like :

for ix = 1 to _screen.formcount
	nTables = aused(aTablesInUse,_screen.forms(ix).datasessionid)	 
endfor
