@JoeByrne !
As you can see, we're all ready and willing to help any and all.
If you would, please update your profile so that your location appears in the upper right corner of your posts. It will help get more accurate answers to your questions as the season progresses.
You don't mention what kind of vegetables, but be aware that some do require pollination to produce.
Also, make sure that your garden is getting plenty of sun during the day. There are very few vegetables that will produce if they don't get enough sun.
