Hello,
could not find space (100 bytes) for variable
The error message is saying you have run out of RAM on your target device. You need to use less variables or switch to a device with more RAM available onboard.
Some components e.g. the ESP8266 have a variable buffer you can alter via the component properties to increase or decrease the RAM usage.

Your program was compiling correctly for me using Flowcode 7. Are you using v7.3 and then applied the updates from here.

If your fully up to date and still having problems then please can you post your compiler messages to the forums so we can see the error messages your receiving.

The LCD in your program uses 1K of RAM to store the display buffer this could explain the higher than expected RAM usage. There could be an unbuffered version of the component you could use but this may limit functionality.
However first try reducing the size of the Wifi component's receive buffer and scan buffer properties. Maybe try the receive buffer at 200 or 100.
