When I call my showTableSummary function is gives me a mismatched type error. 

It was working before not sure how to fix it. This is my code for it: 

{
tableNames: tables;
tableSummary: ()!();
// Initialize an empty dictionary

{tableSummary: count get x} each tableNames;
// get retrieves data from the table
// use tableSummary: to assign value to key x

tableSummary
// Return the dictionary
}

Hi  !

Try removing the section where you declare an empty dictionary: 

 

tableSummary: ()!();

 

This is unnecessary as the code can recognise you’re assigning it to a dictionary, given the syntax of the variable name.

Let me know if this works!

Hi Megan,

Unfortunately, this did not work for me either.

Hi ,

Here are some hints to help simplify your function:

count each `. ** tables **- returns the number of rows in each table

list1 ! list2  - joins these two lists together to create a dictionary

If you are still stuck let me know,

Megan
