Hi,

For this you have to record button click some where in the record itself, like two boolean fields for each buttons and mark the boolean as true from the button function.

Suppose if you are clicking the first button then it calls the first button function, here in this you can write the boolean field of first button as True. If the second button is clicked then boolean field of the second button has to be made as True.

Then later while checking the condition, you can check whether which boolean field is True and use the condition based on it.

Thanks
