Open Passing Parameter as a Tasker Variable using Join API

Hi there,

I've successfully set up a Tasker profile and I'm triggering it using a 'text' match in Tasker.
This all works quite well. The thing is, I don't know how to pass a parameter.

I know it can be done, there is some nice help text in the text match screen in Tasker (something like TaskerCommand=:=datagoeshere) but I can't seem to figure it out.

This is what my Tasker Profile looks like

I'm calling this profile with this API call. (This works)
https://joinjoaomgcd.appspot.com/_ah/api/messaging/v1/sendPush?text=WakeUp&deviceId=0123456

What I'm trying to do is pass another ID through that URL but it's not really well explained how to do that because the above example doesn't work.

I've also noticed a slight bug where Join is taking my set variable name of 'wakeID' and setting it as %wakeid you can see that at the bottom of here.

This is bad because lowercase variables in Tasker are only available in the task instance. That means I can't compare this WakeID to itself when its run again. Variables with an uppercase letter in its name are considered global variables.

Please let me know what I'm doing wrong. I feel like there should be much more information on this page.
