You are extracting the latitude and longitude as STRINGS, so instead of having (say) 15.32, you have a text “15.32”.
Add 0 to the value, or multiply by 1. Using a mathematical operation will force the string to be converted into a number, THEN you can use it as an numerical entry.

Thanks for the reply I’ll try your suggestion :smiley:
