Compare strings do not have <= or >= options.

[ndrorian]

From the three compare operations in AI2 the following two do not have <= or >= options.

So, I tried using the blue compare from the math pallet  but that does not work for text fields? 

See block code and Runtime error. I think there are other ways of accomplishing the objective but I also think this is a limitation in AI2.

Use an "OR" block, one for compare: less than/greater than, and one for equals to ?

Here is the rewrite of the SANITIZE procedure.

Tim is correct here. You can combine the greater/less than comparison with an equal comparison using a boolean OR block. The blue math block will attempt to parse the values as numbers before doing a comparison. Note that these have different semantics:

"200" string< "3" = true

"200" number< "3" = false

When you try to pass a string that isn't also readable as a number, the math block will fail with the error you show.

I knew that I can use an OR block.

My request was to improve the compare text block by adding <= and =>.

Thank you
