I have an optional field name "zipcode" in my form whose type is an integer. I keep getting an Error: "Invalid integer value for zipcode" whenever this field is not fill out by the user. Here's my form name and ZSQL Method: <input type="text" name="zipcode" size="5"> ZSQL Method: <dtml-sqlvar zipcode type="int" optional> mysql> describe profiles zipcode; +---------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +---------+--------------+------+-----+---------+-------+ | zipcode | mediumint(5) | YES | | NULL | | +---------+--------------+------+-----+---------+-------+ 1 row in set (0.00 sec) The "optional" arguement in the <dtml-sqlvar zipcode> should not even rendered if zipcode was blank right? Does anyone have any ideas on how I can make this work? Thanks in advance for any comments, Mike --
