Crystal reports selection formula issue

I am having a hard time one last portion of a report I am writing, I haven't run into this scenario and would like to hear some input on this one. Also my first question on EE as I normally just read what others have been through.

So here's the situation, I have a field called {Arp} data within is like CM-2017 or M1-2017  etc.    I have another field call {ARC} it has data that is the first two digits. CM or M1  and I tried to use a parameter that has -2017 and combine that with the {ARC} to select records from {Arp}  
I don't even know if this is possible, I'm just not seeing a way to make this work.  

Any help greatly appreciated.

Hi,
Assuming you are looking to filter records using record selection, you can try something like below based on the information you have provided.
create a record selection content as (assuming your formula for year selection is year)  -->
{Command.ARP} = {Command.ARC}&{?year}

Hope this what you are looking for.

That is almost the solution.

YOu need to convert the year to a string of 4 digits with no decimal palces and no thousand separator

{Command.ARP} = {Command.ARC} & CSTr({?year}, 0,'')

He said he is getting year in -2017 format, which is a string already, hence didn't use string conversion.

Your correct, but this ends up including more than I wanted, but your formula is correct.  I think I have to go about this a little differently due to the other conditions.

way too much to try and explain here I think...but thanks for your answer.
