I have made this function but it is giving error

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[SuccessEHS].[GetDispense]') AND type in (N'FN', N'IF', N'TF', N'FS', N'FT'))
DROP FUNCTION [SuccessEHS].[GetDispense]
GO

Create function [SuccessEHS].[GetDispense] 
(
    @text nvarchar(40)
) 
returns varchar(40)
as begin
    -- emulate vba's val() function
    declare @result varchar(40)
 
    declare @tmp varchar(40)
    set @tmp = @text
    while isnumeric(@tmp) = 0 and len(@tmp)>0 begin
        set @tmp=left(@tmp,len(@tmp)-1)
    end
    set @result = @tmp
    return @result
end
GO

The GO statement only works in SQL Server Management Studio, if you use it from code you don't need to use GO.
You can also use this syntax in SQL Server 2016 and higher:

DROP FUNCTION IF EXISTS [SuccessEHS].[GetDispense]

Okay but I am using this in Visual Studio in .sql file.

GO statement only works in SQL Server Management Studio, so you will have to delete those lines !
If you want to remain 'compatible' you can also delete these lines on the fly in your code.

Here is a routine to execute SQL commands from an embedded resource SSMS script with GO commands:

public static void CreateDatabase(string server, string catalog, string username, string password)
{
	// get the stream
	Stream stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("MyNamespace.DatabaseUnicode.sql");

	if (stream != null)
	{
		var sr = new StreamReader(stream);
		var script = sr.ReadToEnd();
		sr.Close();
		stream.Close();

		var connectionString = GetConnectionString(server, string.Empty, username, password);
		using (var connection = new SqlConnection(connectionString))
		{
			connection.Open();
			
			if (connection.State == System.Data.ConnectionState.Open)
			{
				// replace it with the correct catalog name
				script = script.Replace("##ArchiveName##", catalog);

				IDbCommand command = connection.CreateCommand();
				command.CommandType = CommandType.Text;

				script = script.Replace("'", "''");
				script = script.Replace("\r\nGO\r\n", "\x07");      // "GO" is not a Transact SQL command, but utilities command
				script = script.Replace("\r\ngo\r\n", "\x07");
				script = script.Replace("\r\nGo\r\n", "\x07");
				script = script.Replace("\r\ngO\r\n", "\x07");

				string[] arrBatches = script.Split('\x07');

				for (int i = 0; i < arrBatches.Length; ++i)
				{
					string scriptBatch = arrBatches[i];
					if (scriptBatch == string.Empty)
					{
						continue;
					}

					string sqlScript = string.Format("sp_executesql N'{0}'", scriptBatch);
					command.CommandText = sqlScript;
					command.CommandTimeout = SqlCommandTimeout;
					command.ExecuteNonQuery();
				}
			}
		}

		SqlConnection.ClearAllPools();
	}
	else
	{
		throw new Exception("The resource sql script could not be found");
	}
}
