Is there any way to check if multiple variables exist in the same if statement? Right now I am having to writing multiple nested if statements but can be quite cumbersome... so just looking for an easier way.

Currently I'd have to write:

<dtml-if var1>

  <dtml-if var2>

    <dtml-if var3>

    <dtml-else>

    </dtml-if> 

  <dtml-else>

  </dtml-if>

<dtml-else>

</dtml-if>

When it would be easier to do something like: 

<dtml-if "var1 and var2 and var3">

<dtml-else>

</dtml-if>

I've tried multiple different methods to accomplish this but haven't had any luck... so is there an easier way to check multiple variables existence in the same check?

Thanks.
