I want to create a Mathematics task on Psychopy

Problem Statement:
I need to design a psychopy task that has 9 sections and some time intervals in between, the first design is the welcome task that tells the participants that they are welcomed to taking this experiment and gives them an instruction that they should input the numbers for all 9 sections and press space after they have inputted all the answer, they have 60 seconds to answer all the questions on each block starting with easy addition followed by hard multiplication then easy and hard subtraction then same for multiplication and division. They can use all the numeric keys 0 to 9.

The stimuli that will be shown to the participants are gotten from my excel file saved on my desktop, all the files are in their individual folders and the title of the folders which the stimuli was gotten and the correct answer to each stimulus respectively is given below: plus the file path
Easy Addition (Stimuli = Task1 Correct Answer = CorAns) C:\Users\USER\Desktop\Final Design\Easy Addition
Hard Addition (Stimuli = Task1b Correct Answer = CorAnsb) C:\Users\USER\Desktop\Final Design\Hard Addition
Easy Subtraction (Stimuli = Task2 Correct Answer = CorAn) C:\Users\USER\Desktop\Final Design\Easy Subtraction
Hard Subtraction (Stimuli = Task2b Correct Answer = CorAnb) C:\Users\USER\Desktop\Final Design\Hard Subtraction
Easy Multiplication (Stimuli = Task3 Correct Answer = CorA) C:\Users\USER\Desktop\Final Design\Easy Multiplication
Hard Multiplication (Stimuli = Task3b Correct Answer = CorAb) C:\Users\USER\Desktop\Final Design\Hard Multiplication
Easy Division (Stimuli = Task4 Correct Answer = CorAnss) C:\Users\USER\Desktop\Final Design\Easy Division
Hard Division (Stimuli = Task4b Correct Answer = CorAnssb) C:\Users\USER\Desktop\Final Design\Hard Division
Mixed Operation (Stimuli = Task5 Correct Answer = CorrAns) C:\Users\USER\Desktop\Final Design\Mixed Operations

Design problem:
I designed the first task and all the stimulus together and it ran but when I shared it to the different folder since I needed the participants to have at most minute and rest, the next task didn’t come up and also, if a participant makes a mistake, he can’t delete an already imputed number, I added the delete button but it recorded the delete button as part of the answer instead of deleting the prior response.
Finally, I need the participants to have access to a timer so that they are not calculating their remaining time in their head and lose focus of the stimulus appearing in front of them

Please, if you can help, I will be most grateful

Hello @Pascal_David

I guess you have to show us how you implemented the experiment.
