adding another parameter when posting

[emath]

ive an help forum, which helps students to solve problems from a books.
and i want to collect all these solutions into one table so i could do a search in that table and find a specific solution easy.

im trying to add some more parameters(actually 3) to a specific group when they are posting .

like there is the "title:" parameter, so i want to add there also "book name: " , "page number : " , "exercist number : "

i succeed to add the parameters next to the "title:" and the textbox,

but i just dont know how to add the data to vbulletin database , or how to create the table for it, i need to do it manually ?

please help me.

regards,
