How to get value of attribute of workflow

Hi,

I want to debug the proedure ,

I want to get the value of attribute from plsql code that is executing workflow.

By declaring anumber column I assign the value by using wf_engine.getitemattrnumber

low := wf_engine.getitemattrnumber

(itemtype => p_itemtype,

itemkey => p_itemkey,

aname => 'HOW_MUCH_WAIT');

As the workflow is not working want to know the last value .

Any suggestions?
