I want a tasker task that reads sms from a particular person, and, extracts some information out of the latest message...

For e.g. I get a lot of messages from my bank due to transactions I make. At the touch of a task I want to know my latest bank balance. Normally, I would get the latest sms from my bank and find out the balance from it. I want tasker to do this.

I am aware that tasker can read messages when they arrive. But we have to make a profile that does it. This is not my usecase. Its more on-demand.

Is this possible in tasker?

Here is the task I tried to create to that effect:

Flash Roam (10)
    A1: Java Function [ Return:cr Class Or Object:CONTEXT Function:getContentResolver
{ContentResolver} () Param: Param: Param: Param: Param: Param: Param: ] 
    A2: If [ cr !Set ]
    A3: Flash [ Text:Ok Long:Off ] 
    A4: End If 

I am unable to ascertain if cr is null or not.

What is the correct way to check it?
