Getting Error The operation + cannot accept the arguments:

[Per Vinsth]

Hi

I reused code from an earlier project but changed some and added a lot of stuff. Now I get this error The operation + cannot accept the arguments: , [test.csv], [1]

I can´t find where it´s wrong can someone help me?

I´m really new to app making so be nice :) I know the blocks are a mess

In your Button Click event

you are trying to "add" ("+") 1 to a list (global File1)

That won't work, hence the error. There is probably more....

So I rebuilt the app using Quiz as a base but now I get that a it can´t create a csv file cannot accept the arguments empty strings. Can you give me some pointers in what I´m doing wrong.

The app should like this.

One screen

Several questions which one have to give an answer to

All answers is saved in a csv-file.

And then when all questions are answered I would like to start again from the top

To resolve the empty string error, replace the text block with a create empty list block.

Also, not sure what you intend further down in the Next Button blocks

you save a file with the name "global file" (OK so far)

Then you set global file as a list further down ??

Okej I did thoose corrections and some other things. But the one thing I can´t solve is to save data to the csv file. It´s still empty. I added a procedure and also a canvas (read it in the forum that it could help) but didn´t help.

I took some stuff from an other app than I built that actually saves data to the csv-file but that didn´t help either. Can you please provide some assistance

[TimAI2]

Nothing in the csv because you are saving "nothing" to it

You built the variable "note" then do not do anything with it.

Try adding the blocks indicated below:

(Also change the name "procedure" to something more meaningful)

Does that help ?

[Per Vinsth]

Almost. I get Error 2103 The file storage /......./port.png could not be created

[TimAI2]

Not sure why you need to save the canvas image ?

Try without those blocks
