Can you make it validate a range of dates? IE a booking form. Just a thought in the pot...

A script can do just about any form of manipulation of data. depending on the ability of the scripter. I am currently getting values into known variables from a csv file. Could be a MySQL database but I work on flat files.
A csv file can have any number of input values, I intend to commonise this to var1, var2 and so on.
then I can work on var3 do something with var6 and var10. A csv file example:- name,email,address,age
I have to work out if many rows are to be included then each variable becomes an array of a particular item
Once I get some manipulations working I can program it into an app. Individual scripts for a particular purpose are easier to create.

By the way if you have a specific problem contact me and I will give it some thought, believe it or not it is a hobby and I get a buzz out of it.
