@smmiloy23 : Add tags in your 01-deploy-fundMe.js deploy script :

Like this : module.exports.tags = ["all", "fundme"];

And you didn't send your 01-fundMe-deploy.js file but instead you send your 00-deploy-mocks.js.

So, check your 01-deploy-fundMe.js if there were no tags present, add these in, just like you did in 00-deploy-mocks.js at the end!

@smmiloy23 : If you don't have the 01-deploy-fundMe.js file, I'm pasting one below :

And also rename your above mocks script that you send to 00-deploy-mocks.js.

const { network, ethers } = require("hardhat")
const { networkConfig, developmentChains } = require("../helper-hardhat-config")
const { verify } = require("../utils/verify")

module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId

    let ethUsdPriceFeedAddress
    if (chainId == 31337) {
        const ethUsdAggregator = await ethers.getContract("MockV3Aggregator")
        ethUsdPriceFeedAddress = ethUsdAggregator.address
    } else {
        ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
    }
    log("----------------------------------------------------")
    log("Deploying FundMe and waiting for confirmations...")
    const fundMe = await deploy("FundMe", {
        from: deployer,
        args: [ethUsdPriceFeedAddress],
        log: true,
        // we need to wait if on a live network so we can verify properly
        waitConfirmations: network.config.blockConfirmations || 1,
    })
    log(`FundMe deployed at ${fundMe.address}`)

    if (!developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY) {
        await verify(fundMe.address, [ethUsdPriceFeedAddress])
    }
}

module.exports.tags = ["all", "fundme"]

module.exports.tags = ["all", "fundme"]
This line fix the problem !!!!
Thanks a lot !
You just saved me !!!
