**Dear Node-Red´s**

**I do have a problem to hand off informations only if a "Store" button is pressed. My flow looks like this:**

You need to _format_ the code correctly when posting.

If I am reading what you said correctly:

inputs are giving you information and you only want it stored if you press a button?

Question though:

How fast is the information arriving?

If it is arriving too quickly there will be problems.

Putting that aside:  
A message arrives. It is _stored_ and if you press _the button_ it is saved.

You can do this a couple of ways.  
But basically the idea is like this:

Message arrives.  
_Store_ the message in context.  
If you press the button, that message is then passed to the output - to the next node.  
Otherwise just store the next message when it arrives.

I use the Q-gate node ([here](https://flows.nodered.org/node/node-red-contrib-queue-gate)) for this type of things... It stores messages based on various conditions and can be setup to release messages via a trigger message sent when a button is pressed.

Dear all  
thanks a lot for your feedback. I will look for the Q-Gate button, which seems to solve my problem.  
... meanwhile  
after a lot of testing I solved my problem by adding a trigger node infront of the store function. This trigger node fires every 0,5 s the information into the store function and wenn the "Go" Signal arives the Stor function sends out the stored message.

Problem solved  
You can close this treat
