I have 4 fields, Year1, Year2, Year 3, Year 4, after entering values in Year 1, User than just click a button, a dialog box will pop up, asking, what percentage I want to use? (with default value is 3%), user once click okay, another dialogue box will pop up, asking which field should it be affected, user can click all fields, (which will than check all Y2 to Y4 fields) or he can just select any of Y2,Y3,Y4. Than, system will get value from Year 1, times with 1+3%m than input value into Year 2, thank, will get Year 2 values, time with 1 + 3%, etc. I am not an expert in script, was looking at using @function formula, but I think it may be too messy?
I am currently using in client environment, any helps are appreciated.
