How do I match a string in an array with variable?

Array For each X element

--> System Array.CurValue = globalvariable1

The global variable is always lowercase with no non-alphanumeric or spaces.

The array contains capitalized words with non-alphanumeric.

Example:

Array.CurValue could be Hello.

globalvariable could be hello

It does not recognize a match because of the uppercase and period. I originally had lowercase(Array.CurValue) but then this does not resolve the "."

Then I tried find(aTexttoArray.CurValue, "[^a-z]"). Also did not work. I tried variations with the Regex expressions but could not get the right code. Any help would be appreciated. Thanks!

You can remove the period and convert to lowercase:

lowercase(replace(Array.CurValue, ".", ""))

If there are many such characters that you need to remove, it may be easier to use a local variable:

set t to replace(Array.CurValue, ".", "")
set t to replace(t, ",", "")
set t to replace(t, ":", "")
set t to replace(t, "!", "")
set t to replace(t, "?", "")
set t to lowercase(trim(t))

You could use Find with a Global Variable(String)

Thank you!!
