Error on quotation save

hi, i found out that the problem is something related to tax section. when i enable the tax as 5%, this error is occurring. whereas if i am not adding the tax amount for my quotation, i am not getting this error. it saves as draft and then i can submit it… please guide me how to fix this issue.
