Substract from variable

Help
1

Hi,

I just started to learn UiPath and at the stuck with the following task: there is a flowchart for processing the invoices and inside of it there are two sequences, I need to subtract one from the processingIndex variable (Int32). How to do it? Can we match variables to the sequence?

Thanks in advance!

What exactly do you mean? To give more details about the flow chart?
