Adjustments to Mobile App Development

We recently got an application developed to collect farm production data and out put the information into excel for analysis and reporting. The app is working relatively well but we need a few changes made to it to tidy this up and finalise the app in its entirety. All the source code is attached along with the applications. we're looking for a relatively fast turn around on this project as we need to deliver the completed project to the client by the end of the month. The changes we need made are as follows: Lists 1. Cant delete equipment if no fuel rate is entered 2. Needs a list for the season to prevent typos 3. Looks like crops are locked on to a paddock in the lists but these will change every year Costs 1. Next/previous skips date field 2. Fields don’t clear after add is clicked Harvest 1. Next/previous skips date field 2. Fields don’t clear after add Rainfall 1. Next/previous skips date field on rainfall 2. Fields don’t clear after add Export 1. Whats with the txt files 2. None of the fields clear after export either, but they should clear after "add" There is opportunity for future application development for the right developer including a full scale redevelopment of this app, to take the application to an online reporting system and include livestock production Upon completion we will require the applications for both android and apple devices as well as the full source code for reference.
