I have a custom list in SP13 with a choice column containing 'Yes', 'No', and 'NA' drop down values. If the column value is marked 'Yes', I want to require the user to attach a related file to the record.
OOTB SP13 Choice type column is named Commercial Bus. Drop-Down Menu choices are Yes, No, NA. "Yes" requires a Commercial Bus Request Form be attached before the new (or edited) form can be saved.
I've seen one JQuery solution on here but from the post I an unable understand the JS syntax required for the script to recognize the column and option combination as a pre-save event. Could this be handled with column validation or is it strictly a JS solution. Any help is creating a formula or JS solution that I can place into a script editor box on the list New Form and Edit Form aspx is greatly appreciated.
