check box

<input type= "checkbox" name= "checkbox" Value= "a" >
<input type= "checkbox" name= "checkbox" value= "B" >
<input type= "checkbox" name= "checkbox" Value= "C" >
<input type= "checkbox" name= "checkbox" value= "D" >

In this case, the Name property of the check box is the same, so that a control array is created, and when returned back to the background, the selected checkbox is connected in sequence with "," and if we select B and C, then use
Response.Write Request ("checkbox") returns the B,c

You can use split to isolate an array, for example
Bb=split (Request ("checkbox")
For each B in BB
Response.Write b
Next

This shows the value of the selected checkbox.

Case: multi-directional deletion!
