For Loop is not looping the numbers i want

i am trying to use forloop as a method to send in multiple data, however, the number that i want to loop is not the one i want to sent in. For example, when i allocated 1 - 5, it only stores in the data 1 - 2. And everytime no matter how many different amount i allocate, it only stores in 2 data, instead of the amount i required. I believe is the method of me looping got error. Please help. @allocate.php
