Thanks for your help.")* Hi, You can't do that. You can only define the number of times the product can be sold. And in the settings of the custom field where the dimension is entered, you can use the regular expression check setting to define the minimum and maximum length that can be entered in the field. But there is no mechanism to calculate the total purchased length against an available length to restrict this. That would require the development of a separate plugin to handle it.
