PF DESIGNER - Error adding new variables in flow

how can I attach screenprints of errors?

Hi Scooter,

You can insert an attachment by clicking the "Attachments" button at the bottom of the page. 

Note that once the original question is posted, you have to click the "Reply" button rather than using the quick response. Otherwise you don't have the attachment option.

BELOW ARE DETAILS FROM (2) ERROR MESSAGES WHEN ATTEMPTING TO ADD A NEW VARIABLE ON "START" NODE.

TRIED ATTACHING SCREENPRINTS FILE BUT LAWSONGURU.COM IS ASKING FOR A PASSWORD FOR "Server at DNNAPI".

Tried my Lawsonguru password but would not work.  THANKS, SCOOTER

Ah, yes, the Null Pointer Exception errors! I've been dealing with that also, and Infor acknowledge the situation and offered no solution.
You learn pretty quickly that you can't add a variable when a Start or Assign node is maximized. You can only add it when minimized.
Once you get the error, you have to click on some other node in the flow and come back to the node you want to add the variable to, minimized, and it will work.
Frustrating, but after a while you get used to it.
