I am having difficulty adding array variables.
My approach has been to add an array variable in the page properties dialogue. This variable is count()
I have two text input boxes. In the properties dialogue I store the input to variable count(0) and count(1) respectively
I have a text (txt_tot) which displays the variable tot_count. The trigger is key press return, x=(?) tot_count = count(0) + count(1)
But nothing happens
I have tried adding the action show txt_tot but to no avail
I am sure that the solution is staring me in the face, please point me to it.

maybe it's a typo but it's

tot_count = count[0] + count[1]

not curly brackets.

Thanks for your help but I am still missing something simple. The task is to create an intereactive web page to determine how to distribute batches of brew-on-premises wines among members who "buy in" in multiples of 30 bottles. e.g. 10 shiraz, 10 barolo and 10 chardonnay. It is easy using excel but that means I have to balance the quantities just because fred changed his mind! The hope is to let them see the consequence of their change. We currently have 10 members and brew 4 times a year.
I attach my humble effort trying to get three numbers ( wine1[0], wine1[1] & wine1[2] ) to add up to wine_tot
I hope the thought of 1200 bottles of wine will inspire your reply.

Two things:

1. The text box will not pick up the return key action as the input boxes have focus.

2. The contents of the arrays / input boxes are treated as text thus your values would be concatenated rather than added.

I've added a button to handled the totaling, though there are other ways and I've used parseInt to return the whole number value from the input boxes. If you need decimal values use parseFloat.
