I need help with a runtime error

I am trying to make an app that counts steps and when i hit start it says "The operation + cannot accept the arguments: , [""], [1]
Note: You will not see another error reported for 5 seconds."

Please show your relevant blocks.

Just guessing you have an empty list or other component and whatever is calling it is expecting content


i also have another one with the same error. the whole block is "when screen intialize"image

i think i found the problem though lemme check. i thought about it a bit more

AI2 cannot add 1 to "nothing", or test if it is less than / greater than nothing ( I am guessing your .text is empty to start with)

Set Pasi_sistem.Text to 0 (zero) on initialisation, then you will be OK.
