Urgent help required for adding current time to a time duration showing a future time

[willemuk]

I am doing event driven programming for a subject at college and normally use vb.net but have chosen to try my hand at Flash script instead. I have created a parking meter using drag and drop functions, etc. and it works great but I have hit a snag and am trying to write a script that adds the current time to a chosen duration time that then shows a predicted time in a text box. I have spent weeks trying to sort the script out but just cannot figure it out. I can get it to show the two times together side by side in the text box but cannot add them together. Here is the script I have written the script in red shows the current time format and the script in blue shows the additional time that needs to be added to it to give the future time prediction. the script in green is roughly what I need it to do but obviously it is not the correct way. Any help would be very much appreciated. Thank you.

First, if you plan on posting code, you should place it within either "[ PHP ] & [/ PHP ]" (note without the spaces) braces so you reduce the annoying scrolling, help with formatting and color coding which makes the code much easier to read.

Secondly, I did read through most of your code, but it looks like you are trying to add time to a string, instead of adding it to the date object. Best choice would be to convert the date/time stamp into a true Date format, then using getTime(), add or subtract to get the desired math. Once you get the new information, then you can convert to string to maintain your two digit formatting.
