i am fairly new to Visual basic and i am curently using it in a project for ict. I have desided to also create a till like system.

Here is my problem,

I have many VB buttons on my till system each relevent to a single item of stock. what i want is for when i click on a button it adds a set amount to a textbox and that keeps a runing tally if i press another button, e.g. press buton 1 and it adds 0.6 to textbox1 and then i clik buton 2 and it adds 4 to textbox1, then textbox1 wud equal 4.6
i have tried such things as "textbox1 = textbox1 + 0.6" but sadly it doesnt work. i wud be greatly releived if sumone cud email me with an answer as this is the only prolem i have left in my coursework.

No real idea what this has to do with XSLT. Perhaps you need to convert textbox values to numbers before adding though.
