PDF Error

[Anon]

Any ideas why I should get the following error reported from some users/pc configurations but not others...

Error executing SELECT CONCAT(s_name, ' : ', brief) FROM tblScales WHERE
qst_id = AND scale>0 AND scale<90 ORDER BY scale LIMIT 20 statement
error:1064 You have an error in your SQL syntax near 'AND scale>0 AND
scale<90 ORDER BY scale LIMIT 20' at line 1

Thanks

because qst_id does not have a value. You should check to make sure user entered information is valid before putting it in ANY sql statement.

if($qst_id) then blah...

or better yet if (is_int($qst_id)) blah...

you get the idea.
