How to display and connect a numbered random output .. Help!!!!

[tsuoshiro]

hi...I would like to ask again, if you dont mind, like i said earlier (if you read my earlier post) i am generating a random questions.. i have a problem (again) on how to connect/combine the first random (test1) to the second random (test 2) questions.. its like combining/connecting/continuing the numbering of test 1 and test 2.

 

for example, for the easy category, there are 30 questions... i will connect it to the average category (let us say it contains 20 items).. how can i connect it...

hope my question is clear.. thanks again and hope you reply...
