URGENT Questions.... for an Question grader sorta

ok a long post...
Alright I just started using zoho creator after i found that it was almost like google spreadsheets in that it could create forms...
but i found it to be a lot more useful put getting the right input...

however, i'm planning to use the application to 1. get students answers for quizzes 2. store their answers on the database 3. grade them and offer a grade report showing how many they got right and percentages of questions they got right to show which places they need improvement on.
//i'm trying to go for "automatic" here... so it should just be able to accept the correct answers and the student answers and figure out percentages and scores..

however i cant find any scripts on how compare any values.. and the documentation for deluge is... just not there (or i cant find it) because i can find a lot more help from the errors i get to use random keywords that were not explained in the documentation...

since using zoho creator by itself doesn't work (right now at least) ... i decided exporting the files to somewhere else to grade but i don't know where... and trying to import the database to zoho db doesn't make sense because its just not integrated enough...

so i would either like a whole lot better documentation on the scripting language of deluge.. such as like any functions or keywords i could use to program.. like a for loop (but only to repeat a process and not the for each loop already specified) or anything like simple functions like maximum value in the database...

an example of not a lot of documentation would be like finding that u can use keywords like "count" or use "captcha = true" or hide|show|enable|disable|clear..
i would like a sample that could display basically every thing you could try... =) so ya specific examples of code being used thats not usually available through the gui because its not very customizable then..

or someway to grade scores...
basically if i asked them to do some practice questions from an SAT booklet... i would just take the answers and upload them to the form.. and then the students do likewise... and then i make a report that tells them how well they did and which question types they need to work on..
or someway to integrate the form with another application...

thanks..
