This is a very simple Elevator(Lift) app. When MoveLiftToTxt goes unfocus the Lift should go up or down. Initially everything is set to 0 the Lift is at the bottom.

I type 10 in the Move Lift and go unfocus the Lift goes up perfect.  
Error Message has “10 and 0” and “up” messages  
I type 3 in the Move Lift and go unfocus the Lift goes up??  
Error Message has “3 and 10” and “up” messages  
The Logical \< comparison fails.  
Both the Move Lift and Lift Pos inputs are numeric.  
Why should the logical \< comparison fail? Just baffling. Please help.

I just checked some posts like this and I’m guessing (since I can’t see where you define movelifttotxt), that movelifttotxt is still text.  
To convert it to number you can have it to equal movelifttxt + 0.  
See the post below for further information.

> Hi, @Patrick_Elisha! wave I think today an issue is coming while comparing numerals. An alike question was answered today by me - [[Solved] Problems with numbers from Labels - #4 by kartik14](http://community.thunkable.com/t/problems-with-numbers/463414/4) These blocks could help you - What I did? I just added a \<textInput(A/B)\> + 0. It doesn’t change the value of the textInput, but (I think) it converts the text to proper numbers, so we can compare. Hope I helped you slight_smile Thanks! blush

Hi Thanks for the reply but I had initialized it as numeric 0 when clearing and I knew the +0 trick you mentioned but since it was initialized to numeric 0 I thought it was redundant. However your reply and the images you shared helped me to rethink my basic algorithm. My Y value was being calculated wrongly. I just fixed it. Now the other bugs are also gone. Thanks
