Want these extensions,can anyone make them

Simply set your global variable v to the value of the tag speed when it is returned in GotValue …then call drawGauge.

Do not call drawGauge in your initialise block because the value in v will be the default (10), not the firebase value.

there’s an error

this is my block

help me, please :slightly_smiling_face:

Global v is empty and math blocks “hates” empty strings. If tag not there set value to 1 for example instead of empty string. Make sure you are using correct tag and that you are getting value from firebase

i’ve tried to fill that with 0 and string " " (empty), but i still got an error

What is global v showing after you get the value from tag speed ?

Not seeing any issues here:


I’ll try it again, thank you so much! :pleading_face:
