Question: I was wondering, is it possible to have for instance a jenkins multijob that contains a "job" select input parameter ?

I want to create a multijob that : 

1 - run a job A

2 - run the selected job (for instance "Hello\_world")

3 - run job B

Finally i got this right, The way might be some what different but it work for me !!!

Here is the code for the same.

```
AttributeUpdates: {
                     Address2: 
                     {
                        Action: "DELETE"
                     },
                  }

```

And then i am adding the value on the condition.

```
if (propertyObj.address2) {
        params.AttributeUpdates.address2 = {
            Value: {
                S: propertyObj.address2
            },
            Action: "PUT"
        }
    }

```

Thank you to all from bottom of my heart :)who tried to help me, Cheers !!!
