Issues adding portfolio to my submission

Sometimes when you are adding your work from your portfolio to a  submission, you may not be able to move to the next step. This will be because you are either missing some details, such as the price of your work, or you are adding files which are not being accepted by the organisation. Alternatively, there may be too many works being added. It is best to look at the guidelines carefully to check that you are adding the correct files. You may need to make some changes or remove some files to continue.
