Action_tile Evaluating

  (action_tile "opt1"  (if (= 0 (atoi (get_tile "selections11")))

		(set_tile "error" "Select #1 Sprinkler from list")
		(nest1) 
		))

Hello people

I'm stuck here:

Basicly, I want to see if statement true, than set the error, if not, run "nest1" (expression i build with defun)

but no luck.Can somebody show how things work with action tile I think should put " " here and there, but when and how

thank you

Expression must be of type string

(action_tile "opt1" (strcat "(progn (if (= 0 (atoi (get_tile \"selections11\")))

(set_tile \"error\" \"Select #1 Sprinkler from list\")
(nest1) 
))"));check brackets

Just on the quick glance

amazing forum:thumbsup:

(setq Ldist ( getdist \"Get Distance\")))")) (start_dialog)
