if elseif elseif else in netlogo

I want to have a if elseif else if else structure in netlogo but it seems that at the moment it is not working.

  ifelse random 100 < 68 [ set HBB-Genes "A,A" ];;68%
         [ifelse random 100 < 2  [set HBB-Genes "S,S"] ;;2%
         [ifelse random 100 < 15 [set HBB-Genes "A,A"];;15%
         [set HBB-Genes "A,A"] ;;15%


         ]]

I would like to have a 68% chance of occurring the set HBB-Genes with "A,A" and the next one with 2% chance of occurring and so on. If anyone has experience with netlogo and can help it will be much appreciated. Thanks.

You only want to pick one random number, not several. You can use let to store the random number so you can refer to it later. So:

let chance random 100
ifelse chance < 68
  [ set HBB-Genes "A,A" ]
  [ ifelse chance < 70
      [ set HBB-Genes "S,S" ]
      [ ifelse chance < 85
          ...

And so on.

It can be done in the following way with if statements otherwise the next if statements got the remainder of the chance of occuring.

if geneNumber <= 68
       [
         set HBB-Genes "A,A"
         set color blue
       ]

        if (geneNumber > 68) and (geneNumber <= 83) 
       [
         set HBB-Genes "A,S"
          set color green
       ]

       if (geneNumber > 83) and geneNumber <= 98
       [
         set HBB-Genes "S,A"
          set color green
       ]
       if geneNumber > 98
       [
         set HBB-Genes "S,S"
         set color red
       ]
