Forums Scripts & Popups if-then-else statement

Sorry, I misread your original post. Try this.

if ((%abc != $true) && (%cbs != $true)) {

This will not execute if either variable is set to $true. With this you could either unset the variables or set them to anything except $true.

You could also try this

if ((%abc != $null) || (%cbs != $null)) {

This would trigger if either variable is set with any value at all.
