Hello and thank you. I have one table (Tasks Table) which contains tasks information, skills and durations. The idea is to schedule these task considering skill availability and current loading per time unit. Selecting a row of this Task Table brings up the Availability/Loading information for that skill set clicked on. This is purely summing duration by selected skill and date and will be presented in a second table. In this second table I would like also a selection box which allows changing the skill set directly instead of clicking on the table row. I am very new to the web development, mysql, PHP etc. I have build this years ago in Excel and would like now to make an improved version as a web application. Right now I am trying to get a direction in my head which way to go with this, what is possible what is not. Been using internet search and books to help me with that. I guess what I struggle most with is the PHP Server, Javascript (Client) concept. Thanks again.
