Use part of the name of a comp in expression

Hello there,

I want to use part of the name of a comp to automate the actualization of expressions when duplicate this comps and the precomps in them. I labeled them as name_twodigitnumber, so I was wondering if there is some way to use Comp.name or a similar expression to get just the ending two digits number of the name of the comp as output, so they can actualize automatically when I make some duplicates. Hope the explanation is good enough.

Thanks in advance.

Diego.

Something like this would give you the number:

parseInt(thisComp.name.split("_")[1],10);

    Thank you Dan. That seem to do the trick. Nonetheless doing several tests I came up with something like this below, as long as I still do not get how parseInt work exactly, and I prefer to go slow or workaround in order to understand what im using.

    I want to get an "N" output referring another composition called "Holder_XX", where XX is a number with two digits, so I used this:

    N=comp(("Holder_")+thisComp.name.split("_")[1]);

    In order to increase automatically the "XX" (two digits number) by the name of the composition where im writing the script (name_yy).

    Best regards, Diego.
