Probl. med restaurant_add & formvar.tcl : LUSENET : WebdesignII : One Thread

Jeg får fejlmeddelsen: wrong # args: should be "proc name args body" while executing "proc chk_seq_id {form_var {err_msg " "}} { upvar $form_var seq_id if {![info exists seq_id] || ![regexp {^[1-9][0-9]*$ $seq_id]} { ..."

Example email addresses are

Det ser ud til at du i linie 74 i filen formvar.tcl har glemt en slut-tuborg } i slutningen af møstret.
