Use PUMS data for PUMAS belonging only in one county

Hello! I try to use PUMS 5yr 2008-2012 data and I face a strange fact that when I sum the weights (variable PWGTP in the dataset) for the PUMAS that belong to a specific County, I do not take as a result the known total population in this county (compared to the population from ACS 2008-2012 estimates)...
Could anyone advise me if I use the given weights properly? The PUMS data are for PUMAS in one whole state and I try to extract only the PUMAS in the county that I need. Is it possible or there is problem because the PUMS data are defined at a state level?

    Yes, I create a new column with values from PUMA10 when PUMAA00 is equal to -999. But how can we estimate the total population from the given variables?Is it ok to add the weights given in variable PWGTP within the dataset in order to take the total population in the corresponding area of interest?
