The input needs to be created in the pre state so that the value is assigned, then you need to start the post process
#show
'<table id="fck">
'<tr><td>'f_ck = ? '</td></tr>
'</table>
#post

2 years ago You'd better also put the id in the immediately enlosing element, which is td in your case:
#show
'<table>
'<tr><td id="fck">'f_ck = ? '</td></tr>
'</table>
#postYou can even just use a paragraph element. If you wan't to hide it so that that the user would not put any other values add also display:none style:
#show
'<p id="fck" style="display:none;">'f_ck = ? '</p>
#post

2 years ago Thank you all for the answers, i create another simple code to verify punching with our national code and the problem is similar.
After one calculation, if i try to do it again, all the variables change. see the figure below:
Firts time calculation:
Results:
If i press the calculation button again
Here is the code: ``

2 years ago Hi! Thank's a lot! Great code BTW! :) The problem is that you have input fields "?" in the #post section:
'Tensão Normal
σ_cp = ? 'MPa
'Taxa de armadura
ρ = ? /100You can simply add #show before and it will become like this:
#show
'Tensão Normal
σ_cp = ? 'MPa
'Taxa de armadura
ρ = ? /100
#postTo avoid this problem, always make sure that all question marks are in #show or #pre sections so that to appear in the input stage. In future versions we can make the parser to detect such cases automatically and report them as errors to the user.
Your code is very similar to what we do here to Eurocodes. :)

I get it now! Thank you guys!
@Proektsoftbg our national code have a great influence from Eurocode, personally i use eurocode when some things are missing or need to be clarifyied.
Now i have three last questions:
1) How can i donate to this project? 2) How can i contribute to this project? 3) We have a forum or anything similar to share codes, examples, tutorials?

2 years ago Hi, I am glad you have managed. :) Thank you for your questions. You are so kind!

2 years ago Great!
1) So, open the sponsorship, i can made some small donations when possible, you won't get rich, but you can buy a coffee :) 2) Great! I can try to help, i'm still learning C#, not gonna lie, my first language is Pascal (i know, that's old) but i have acess to some professors in the university where i teach that can be helpful, plus i really like to program. 3) I almost concluded some scripts, i will post in github soon.
Hi,
I trying to create a selection list to a variable called fck, but indepent of the selection made it bring the results of previous variables:
Here is the code:
Someone can tell me what i'm doing wrong?
