I have inspected your form http://www.jotformeu.com/form/52047268577363 and I saw that you have set form limits based on a Unique Question. This means that form can not be submitted with previously entered value.
If you want to allow your users to submit your form multiple times with same value, then set Unique Question to No Check.
More about form limits based on unique question, you can find inside of this guide:
If I did not understood your question correctly, please explain in more details what you are trying to achieve and provide us ID of the form you are working on.
Let us know if you need further assistance.
