Odd recursive function error

I'm getting the following error in a very shallow recursive function (3 to 4 levels of recursion is as far as it ever goes) "Warning : mysql_list_fields() [ function.mysql-list-fields ]: Unable to save MySQL query result in ..." Here's the snippet it's occurring in: function SearchForm($inTableName) { // Breaks on next line when function is called recursively $fieldList = mysql_list_fields($this->databaseName, $inTableName, $this->connection); <snip> } Does anyone have an idea what might be happening? I tried to find the answer on the PHP site but it mentioned the mysql path and default libraries which didn't seem to apply as it works perfectly in the first call. Thanks, Ken
