Interpratating GUICtrlRead single and double digit numbers

[donhorn20]

I have some input boxes where the starting value ($InputFirst) needs to be greater then or equal to the end value ($InputLast). Problem I am encountering is if the starting value is a single digit number, say 2, and the ending value is any double digit number but the first number of the double digit is less then the first input box (12), I get an error for ($InputFirst) >= ($InputLast) statement. It's like it's treating the first digit as its comparison value and not the whole digit for the ($InputLast) value. Any ideas? Let me know if this even makes sense. I included my if statements I have for checking. If I need to provide more just let me know.

ElseIf GUICtrlRead($InputFirst) = "" Then
MsgBox($MB_SYSTEMMODAL, "", "No Values.")

ElseIf GUICtrlRead($InputFirst) >= GUICtrlRead($InputLast) Then
MsgBox($MB_SYSTEMMODAL, "", "Start is greater then End.")

ElseIf GUICtrlRead($InputFirst) = 1 Then
MsgBox($MB_SYSTEMMODAL, "", "Start needs to be < 1")

Convert them to numbers before comparing them

ElseIf Number(GUICtrlRead($InputFirst)) >= Number(GUICtrlRead($InputLast)) Then

Thank you very much BrewManNH. I knew I was missing something simple like that. It is working now.
