Hi . I’m knitting a sweater with cable patter Rddec and Lddec which i understand however next roe says decrease 2st (2st inside stitches as in 3rd row which is the cable row. Can u help.

Can you tell us the name of your pattern and the designer or source?
How does your pattern define Rddec and Lddec, double decreases?
Sorry for all the questions but can you quote the 3rd row of the pattern exactly?
