Help with coding a Calculator into my site

Hi There
Is anyone able to help with coding a calculator to add to my site so people can put in their wall measurements and it will tell them how much wallpaper they will need.
Please see two examples below and let me know if someone can help and what the cost would be.

Thanks
Grace

Grace, this is actually not that difficult. There are a couple of ways to do it, but I would go for a LightBox, to do the calculator. Most time (for an external developer) will be spent at what you want (cm only, or also inches), how the calculations are done, where do you get the “repeat pattern” info from, etc.
Shouldn´t take more than a couple of hours.

Hi Giri

What I wanted to do rather than offer by the roll is offer by the panel. Then they dont need to worry about pattern matching/repeats. It seems however even when people download my guide to measuring how much they will l need they dont seem to get it.

So I need it to calculate how many panels / lineal meters they will need. Please see my instructions and see if you can help simplify this and if its possible to calculate.

I need something just like on the Sparkk site - they only have a few of my designs up and Id like to put more up on my site but need to get this calculator happening to make it work.

Hi Giri
Were you able to take a look at the above. If you can let me know what it would cost to create this calculator for me ASAP that would be great.
Many Thanks
Grace

Grace, this is such a small project, I would gladly help you out for free. Just one question: are you using Wix Stores or just Wix Code?

Hi Giri
I am using the Wix stores.
I have found another version for you to look at. Whatever is simplest.

Are you able to help if Im not using Wix code?

Thanks

Grace, I am quite comfortable in Wix Code, but know nothing of Wix Stores. I had a quick look at it and I see some limitations that might dictate what we can do. So in order not to spend too much time on it, I´ll ask some questions on this forum, see if anybody else has the answer. I have some questions for you too. Could you email me?
