function SF_Store(uint256 _Index, uint256 _numberadd)public {
    //ABI Application Binary Interface.
 StorageArray[_Index].Store(_numberadd);
}

On this function, I'm running into an error:

TypeError: Member "Store" not found or not visible after argument-dependent lookup in contract SimpleStorage

Hi there, can anyone help me here why I'm getting this error?

Can you share the entire solidity file?

I'm not sure whether you're using StorageArray as a map or an array.

Try this maybe
StorageArray[_Index] = _numberadd;

[alymurtazamemon]

StorageArray[_Index].Store(_numberadd);

You have done a typo mistake here, make sure the spelling of the Store method. @faisalbaloch11

Could you share the rest of the code?

Might of used the wrong form of visibility for Store? Such external, public, ect?
