find specific value from collection 1 to collection 2

[LorenzoCapocci1]

Hi Team, as per example below I need to check if items from collection1 are within collection2 but in collection2 we may find more than 10 results...
At the moment I have set to collection to check for duplicate values, but if the below happens, I need to make sure that I don't get the error (now row exist in collection), so it can check and see if any of the items from collection1 are within collection 2, and move thematching item into a new collection

can you help to find an example to follow?
note from collection 1 there will be no empty row to fill up
thank you

Collection1		Collection2
Form1		Form2
GI13289312		GI13289305
GI13289313		GI13289306
		GI13289307

Hello Lorenzo,
Why not use a filter collection action followed by a decision stage to check existence of item in Col1 in Col2?

For Example, Let us take your collections above and then the below Steps :

Step 1 : Loop Through collection 1.
Step 2 : Filter item of Col1 in Col2 and store in a temporary Collection  -->  [col2.field]='[col1.field]' { Stored in Temporary Collection. Let us call it Temp}
Step 3: Check number of rows of Temp.
              if Temp>0
                    element of Col1 exists in Col2
              else
                     element of Col1 does not exist in Col2
Step 4 : Clear Collection Temp for next iteration.
Step 5: Increment counter in Col1 Loop and start Step 1 unless collection end is reached.

Hello @Ved Sengupta, thank you for helping on this, but I would like to ask if it is possible to have an example of this, as I am still new on RPA, and this would help me a lot, if you could do that.. especially with the code you have provided... Thank you very much​

Hello Lorenzo,
I have got an query.

In Loop Collection2 
Immediately after starting the nested Loop you are checking a decision stage followed by some action.
What value in decision stage are you exactly checking? And From which action are you getting that Value?
