I have just started learning to program (Edit: a tad more experienced now Smiley Happy), so I thought I would try and give something back to the community. If anyone has any problems, please let me know and I will try and fix it as soon as possible!


A huge thanks for all the support, bug reports and general help from the community that has made this calculator far better than it was when I first wrote it Smiley Happy 


Hope it is helpful,

Impressive, I like it.

Nice piece of programming, well done.


Unfortunately on my computer some of the text is wrapping, for example £7.5 is on one line and goodybag on the next which then doesn't fit into the boxes.


The bad way to fix it would be to specify the precise fonts to be used.


The better and more modern fix is the responsive one. Change those px values in your styles to ems. Let the whole table adjust in size according to the users font settings.
