Hi ​@Jane H Happy Tuesday! I hope you’re having a great week so far!

​@john.desborough is definitely your guy when it comes to calculators and variables!

​@Jane H - can you please add a screenshot or a loom/video of the logic rules that you are trying to implement. that will make it easier to answer the question. 

thanks

Hello John,
Ah yes apologies. Here is what I have set up. I am actually struggling with how to get it to calculate the answer. Where do I put that so it displays the total and a summary of each item on the Ending. The variables are at the end but not sure if they are correct either :) I hope the below helps.
Many thanks for looking at this for me.
Jane

Hello ​@john.desborough 

i am wondering if the screenshots I sent last week were useful?

many thanks Jane

Hi Des ​@john.desborough 

my biggest problem is I don’t know how to calculate the result and display it as part of the ending. I am hoping you can shed some light. Many thanks Jane 

A good bed design can really change the feel of a bedroom, especially when the shape and materials complement the rest of the furniture. I like clean, timeless designs that add character without making the room feel crowded. If you’re exploring similar furniture styles, I found some nice inspiration at https://houseoffurnishes.com/ worth checking out.

I’d test the calculation with a few different answers first, especially when optional fields are left blank. That should help spot any issues with the logic. For anyone interested in mobile games, here’s a gta san andreas apk.

Creating a Calculator using typeform

I want to create a simple calculator:
I have these number questions which the user answers:

• Your Fabric cost (per meter)
• Number of metres
• Pattern cost
• Notion cost 
• Estimated hours to sew (optional)
• Hourly rate (only if Estimated hours to sew is greater than 0)

The ending that appears on the screen is:
The cost of your sewing project is: (v_total) with a summery of the costs below
v_total = (Your Fabric cost x Number of metres/yards) + Pattern cost + Notion cost + (Estimated hours to sew x Hourly rate)
All optional questions do not require an answer and if they do not have one, then proceed to the next question. Except if Estimated hours is blank then it skips hourly rate and goes to end.

I have created these custom variables, but not sure how to correctly link them to the number questions. I have had a go with logic branching etc...but don’t seem to have it right.

I’d start by connecting each number question to its matching variable, then use a calculation step to combine the values and handle optional answers as zero. The conditional logic for hourly rate should only run when estimated sewing hours are greater than zero.
