# Errors compiling vppm

Hello,
Most of the CMAQv5.3.2 files are compiling OK (lots of warning messages aside) but the compilation of vppm.F keeps producing the error:

``````vppm.F:341:11:

341 |       DO NP = 1, NPMAX
|           1
Error: Symbol ‘np’ at (1) has no IMPLICIT type; did you mean ‘fp’?
vppm.F:341:22:

Of course I can simply declare NP and NPMAX but I’m not familiar with the internals of the code so it’d be desirable to get some feedback before proceeding to do so. Thanks.
