Check the formula bar to see if the formula is correctly copied. Method 2: Using the CONCATENATE Function The CONCATENATE function in Excel is a powerful tool not only for combining text but also for inserting the dollar sign ($) into your formulas flexibly. This method is particularly useful...
Take a moment to experiment with the code and make sure the property-binding and event-binding syntaxes make sense, both from the “outside” as well as from the “inside.” It might seem odd that you didn’t just use a number for the votes field in the UpvoteC...
The first thing we do is use the IsArray function to determine whether the variable arrSubkeys is an array. If it is, the Test key does have at least one subkey (otherwise arrSubkeys would have no value at all). Because IsArray comes back True, we set up a For Each loop, one ...
If a function’s syntax is not constructed correctly, it can return the #VALUE! error. Solution: Make sure you are constructing the syntax properly. Here’s an example of a well-constructed formula that nests an IF function inside another IF function to calculate de...
